In some[note 2] typewriters, a typist would, for example, type a lowercase letter A with acute accent () by typing a lowercase letter A, backspace, and then the acute accent key. This technique (also known as overstrike) is the basis for such spacing modifiers in computer character sets such as the ASCII caret (^, for the circumflex accent). Backspace composition no longer works with typical modern digital displays or typesetting systems.[note 3] It has to some degree been replaced with the combining diacritical marks mechanism of Unicode, though such characters do not work well with many fonts, and precomposed characters continue to be used. Some software like TeX or Microsoft Windows use the opposite method for diacritical marks, namely positioning the accent first, and then the base letter on its position.
The backspace is distinct from the delete key, which in paper media for computers would punch out all the holes to strike out a character, and in modern computers deletes text following it. Also, the delete key often works as a generic command to remove an object (such as an image inside a document, or a file in a file manager), while backspace usually does not.[4][5]

Pressing the backspace key on a computer terminal would generate the ASCII code 08, BS or Backspace, a control code which would delete the preceding character. That control code could also be accessed by pressing Control-H, as H is the eighth letter of the Latin alphabet. Terminals which did not have the backspace code mapped to the function of moving the cursor backwards and deleting the preceding character would display the symbols ^H (caret, H) when the backspace key was pressed. Even if a terminal did interpret backspace by deleting the preceding character, the system receiving the text might not. Then, the sender's screen would show a message without the supposedly deleted text, while that text, and the deletion codes, would be visible to the recipient. This sequence is still used humorously for epanorthosis by computer literates, denoting the deletion of a pretended blunder, much like a strikethrough; in this case, however, the ^H symbol is faked by typing a regular '^' followed by typing a regular 'H'.
owen_water's suggestion is the same as Carpetsmoker's comment, enabling all three of these. That's generally what people want, since it's a bit surprising to have Vim refuse to let you backspace text that's right there. So take your pick of the two equivalent choices - I'd go with the more verbose and clear one:
I'm currently running HeidiSQL 10.2.0.5669. Whenever I'm in a grid (table data, table editing) and I press backspace, the active tab looses focus and the first tab called "Host [...]" becomes active. Del(ete) works as expected, but.. the number of times I press Backspace and end up in another tab.. well, it's quite annoying. ;-)
Maybe it's that "Go to" menu item which does that, although I don't guess you have set your backspace key as shortcut for it. But maybe it helps to remove the default one (Ctrl + 1), in Tools > Preferences > Shortcuts?
Must have something to do with Wine. As a temporary workaround I downgraded Wine to version 4.1-1 and now it works. In every version above that (tried 4.10, 4.11, 4.12, 4.13, and 4.15), hitting backspace while editing a field in the grid just focuses the "Host" tab.
I can also confirm the behavior. After updating to the current Codeweaver Crossover (Wine 4.12.1), the behavior also occurs in a Mac environment. Because of MacOS Catalina the update to the latest Wine version is unavoidable.The problem does not occur in Heidi's SQL Editor. But if I want to change a value in the data view within a column/cell, the backspace key cannot be used.
I'm using HeidiSQL 10.2 under Ubuntu 20.04. almost on daily basis. It works very stable without any problems (and no backspace problem).The backspace problem is very annoying but with the wine-staging-6.1 (version 6.1~focal-1) there is no backspace problem (i'm using 64bit standalone heidisql version) - works out of box.
I have tried re-downloading Libre Office and opening several different files. I have also checked the keyboard allocation (Backspace = backspace). When I press the backspace key, it deletes one character only, no matter how many times I press it. I cannot backspace more than a single space.
Turn off Track changes, Edit > Track changes > Record (Ctrl+Shift+C). If you want to track changes then delete forward or Ctrl+Backspace to delete whole word behind, or use Shift+Arrow keys or Ctrl+Shift+Arrow to select letters, or words, then backspace. Cheers, Al
However, the backspace key moves the cursor forward instead of moving it backward. I tried to add the stty program to /usr/bin/ of the chrooted directory, do a stty erase ^H or ^?, nothing is done, the problem and the same either from a Mac or Linux terminal .
And yet ... something that surpasses me ... the backspace key works correctly with a non-chrooted SSH connection. And if I chroot the user directory directly from the server with root session for which the backspace works, same problem once chrooted the backspace becomes faulty.
Typically a terminal application doesn't receive a "Backspace" the way GUI application does. It receives a control character, which it will interpret like backspace. The terminal emulator, which is a GUI application, does the job of translating from the GUI Backspace to the appropriate control code, and this can be configured in the terminal emulator's settings. The usual control codes for Backspace can be ^H (the ASCII backspace character) or ^? (the ASCII Del character). Press CtrlV and then Backspace while in your shell to see which one it is.
Hi, The issue only happens on Toad. My backspace and up and down key is working without issue on word, excel, text pad, note pad, sqlplus etc. I looked into Method 1, Turn off Sticky Keys & Filter Keys, and both Sticky Keys and Filter keys are in Off position.
Have not had issues in years and it popped up couple of months ago, I would assume after an upgrade but not sure what upgrade to my work laptop took place. Since this is not a global issue and only impacts Toad can there be a Toad specific solution. One of the old posts from 2009 said to remove PLSQLKEYS.BIN from client files but I did not find such file. I am currently using 13.1.
This is actually an old issue that was fixed a long time ago, but somehow has now resurfaced. My Normal Style is set to indent first lines of paragraphs. The problem that has come back again is that when I press the backspace key, it will not move back to the un-indented beginning of the line. The only workaround I've found for this is to go into the paragraph group and temporarily remove the indent default.
Like I said, this is an old problem that was addressed and fixed at least three or more years ago. Somehow, today, it has just come back again, and it's a real nuisance. The backspace key should take me back to the beginning of the line, whether there's an indent default in the Normal Styles gallery or not.
Trying to delete characters in insert mode with the backspace key sometimes doesn't seem to work. I can backspace sometimes, but at other times it does nothing; the cursor doesn't go to the left, and absolutely nothing seems to happen.
Though the default behaviour may be surprising, the backspace "not working" can be considered a feature; it can prevent you from accidentally removing indentation, and from removing too much text by restricting it to the current line and/or the start of the insert.
By default, the backspace will go to the previous line if at the start of a line (as if eol was in backspace); you can control this behaviour with the 'whichwrap' option through the b flag (enabled by default).
when I have set Notepad++ setting "covert tabs to spaces", so Notepad++ automaticly insert indentation by spaces, cursor is on the start of line (after indentation) and I hit backspace, only one space is deleted, not one whole indentation (size 4 spaces). Is there any setting which control that?
you can always map keyboard shortcuts the way you like them. In this case you can set "backspace" to do the same thing as "Shift+TAB". Just out of curiosity, how do you delete a single space if backspace is set to "unindent"?
Idea is to use the backspace button to delete a point during edit mode when creating a polyline, point or polygon. For example when you are digitizing a lake and you accidentaly place a point that is not on the line, by pressing the backspace button that point is deleted and you can continue with your next point. Currently you have to right click on top of the point and hit delete vertex. This is time consuming and often when you are rushing it takes a few clicks to for ArcGIS to find the point.
So I got my first MacBook today and fiddled with some of the options. I set my mission control to fn, but when my friend told me that fn+backspace is used to delete I decided to change mission control back to what it originally was. I don't know if fn+backspace worden before I did all that, all I know is that it doesn't now. How can I get it to work / change it back?
You can reset the key while logged in by entering stty erase That will set the backspace to whatever character you are sending as backspace for that terminal session. tylerl's response is a better long-term fix.
If the backspace was working okay initially and no longer is then try using the "reset" command. Look around putty's options menu for a "send hard reset" option as well. If it was never working then try what tylerl suggested.
I have performed an upgrade of our editor engine, and I am no longer able to reproduce these issues. Holding backspace with the on-screen keyboard deletes by word after a few seconds, and Cmd+delete removes the whole line now.
Based on your response I would say that's its either an issue with your input device (keyboard) or a network issue. PowerApps doesn't behave like this for me. I can press and hold the backspace button and nothing happens. I can't recreate your scenario. 17dc91bb1f
