How to comment code in VI or VIM


Mark the area which is to be commented using the *blockwise* visual mode (CTRL-V, in Windows this is CTRL-Q).

Press I (capital i) and write the text you want to prepend to each line of the selected block, e.g. #####.

Then press ESC and the text will be inserted to the left of each line of the selected block.
