Window Handling Convenience Features and Customization http://www.ldc.usb.ve/docs/emacs/Windows.html#Windows

M-x winner-mode is a global minor mode that records the changes in the window configuration (i.e. how the frames are partitioned into windows), so that you can “undo” them. To undo, use C-c left (winner-undo). If you change your mind while undoing, you can redo the changes you had undone using C-c right (M-x winner-redo). Another way to enable Winner mode is by customizing the variable winner-mode. The Windmove commands move directionally between neighboring windows in a frame. M-x windmove-right selects the window immediately to the right of the currently selected one, and similarly for the “left,” “up,” and “down” counterparts. M-x windmove-default-keybindings binds these commands to S-right etc. (Not all terminals support shifted arrow keys, however.) Follow minor mode (M-x follow-mode) synchronizes several windows on the same buffer so that they always display adjacent sections of that buffer. See Follow Mode. M-x scroll-all-mode provides commands to scroll all visible windows together. You can also turn it on by customizing the variable scroll-all-mode. The commands provided are M-x scroll-all-scroll-down-all, M-x scroll-all-page-down-all and their corresponding “up” equivalents. To make this mode useful, you should bind these commands to appropriate keys.

para usar isto de maneira transparente aqui vao os passos

adicione a linha no seu .emacs

(server-start)

e a seguinte funcao no seu .bashrc

function emacs {

if [ $(pidof /usr/bin/emacs-snapshot-gtk) ]; then \

/usr/bin/emacsclient.emacs-snapshot -c -a emacs-snapshot $1 & \

else \

/usr/bin/emacs-snapshot-gtk $1 & \

fi

}

para testar

# emacs

# emacs

Terminal dentro do emacs

Emacs + Cscope

To Install in Debian/Ubuntu

sudo apt-get install cscope

write this 2 lines in you .emacs

...

(load-file "/usr/share/emacs/site-lisp/xcscope.el")

(require 'xcscope)

...

Then, if you have code in ~/mycode, cd to that directory and run

Code:

myusernam@mycomputer:~/mycode$ cscope-indexer -r

run emacs

myusernam@mycomputer:~/mycode$ emacs main.c

put the cursor on the word you want to search and

[Alt+x] (and one of the the options bellow)

cscope-find-called-functions
