emacs useful commands

Here are some useful tips from this site.

1. C-s incremental search. Once you have reached the end of the buffer it will perform an overlap search from the start.
2. Use fn+left arrow to move to the end of the current line.
3. Use fn+right arrow to move to the start of the current line.
4. Use fn+up arrow to move to the start of the buffer.
5. Use fn+down arrow to move to the end of the buffer. (These are tested on Aquamacs)
6. M-x grep is extremely useful. It will bring the grep -n -e command to which you must append the filename and the 'string to match' and hit return. The grepped results will be shown in a separate buffer which you can click to move to the appropriate position in the source file.
7. M-x shell opens a remote/local shell on a separate buffer.
8. If a file is in version control then emacs shows that in the bottom buffer bar. (e.g. SVN).
9. C-x v = shows the modifications that you have done since the last commit to the current file.
10. C-x v v will perform the next appropriate version control action to the current file. If it is a commit then you will get a buffer to write a commit note and then hit C-c C-c to make the commit.
11. To enter/exit from full screen mode use: command+shift and return.
