## Shell tips

Did you know your shell has keyboard shortcuts? They are quite useful. Here is a list for the default mode ("emacs mode"):

- `ctrl+r`: search in history
- `ctrl+a` and `ctrl+e` : move cursor to beginning or end of the line
- `alt+d` and `alt+backspace` : delete the word before or after the cursor
- `ctrl+k` and `ctrl+u` : delete the text before or after the cursor (except in ksh for which `ctrl+u` delete the entire line)
- `ctrl+y`: paste the last deleted text

The shell can also be used in vi mode, but this I'll save for another webzine issue.
