TIL about Ctrl-# (for commenting a command), and Ctrl-x+Ctrl-u (or Ctrl-/) for undoing changes.

One shortcut that used often is Ctrl-o. When you have a few commands in your history that you want to repeat in that seqeunce, search for the first command in the group, optionally edit it if you want, and press Ctrl-o instead of the ENTER key.

After this command is executed, the next command in the history is presented to you. Press Ctrl-o again to continue the sequence, or press ENTER once you reached the last command in the sequence.

If you want skip a command in the sequence, instead of Ctrl-o just press Ctrl-n (or down-arrow) to get the next one in sequence.
