 - In Bash, use **ctrl-w** to delete the last word, and **ctrl-u** to delete all the way back to the start of the line. Use **alt-b** and **alt-f** to move by word, **ctrl-a** to move cursor to beginning of line,  **ctrl-e** to move cursor to end of line, **ctrl-k** to kill to the end of the line, **ctrl-l** to clear the screen. See `man readline` for all the default keybindings in Bash. There are a lot. For example **alt-.** cycles through previous arguments, and **alt-*** expands a glob.
 
-- Alternatively, if you love vi-style key-bindings, use `set -o vi`.

+- Alternatively, if you love vi-style key-bindings, use `set -o vi` (and `set -o emacs` to put it back).

+- For editing long commands, after setting your editor (for example `export EDITOR=vim`), **ctrl-x** **ctrl-e** will open the current command in an editor for multi-line editing. Or in vi style, **escape-v**.
 
 - To see recent commands, `history`. There are also many abbreviations such as `!$` (last argument) and `!!` last command, though these are often easily replaced with **ctrl-r** and **alt-.**.
