Tab marks

“Your extension doesn't find all my tabulations” is one of the most common feedback I'm receiving, and this justifies some explanation...

• 1. Pressing the Tab key on your keyboard doesn't necessarily have the effect of inserting a tabulation within your document.

  2. In Google Docs, pressing Tab at the beginning of a new (empty) line will insert a tab, while doing the same at the beginning of an existing line (with text) will increase first line indent, without inserting any tabulation:

• 1. Some characters may look or act like tabs on your screen, while they aren't. i.e. Page Breaks in Google Docs generate a visual indentation that looks a lot like a tab. Same thing happens when copying external content to a Google document: your original text source may contain some outdated characters like form feeds to separate sections, etc., which you could take for Tabs:

Show extension is pretty straightforward —if not dumb— in terms of detecting characters: if there is a tab (ASCII code 9) somewhere in your text, it will show it. If you see something that looks like a tab but isn't spotted by Show, there's a good chance it's simply not a tab.
