In Gvim (Windows Edition), the shortcut key for a block selection is not <ctrl-v>
- The general selection mode is: V (lowercase), which appears: visible.
- The row selection mode is: V (uppercase), which appears: visual-line.
- The most ferocious block selection mode is: <ctrl-q>, which displays: visual-block.
If you want to bulk insert comments, the following sequence of actions:
- Move the cursor to the first line of the comment block.
- Press ESC to enter normal mode.
- Press <Ctrl-q> to enter block selection mode.
- Move the cursor down with the H, J, K, L keys (Note: This can only be moved with these four keys, does not support the arrow keys).
- When the corresponding row is selected, press the I (uppercase) key.
- Enter//, and press ESC to complete the comment.
