Twitter Moment
Shortcuts list

| Meta-# (Esc-then-# on a Mac) | Comment out the current command from the start of the line |
| Ctrl-_ | Incremental undo of command line edits |
| Ctrl-l (lower L) | Clear screen (like the clear command but isn’t saved in history) |
| Ctrl-w | Delete the previous word on the command-line (before the cursor) |
| Ctrl-u | Delete everything from the cursor to the beginning of the line |
