failure if the user does not press 'y'.
|

- `bbpause`: Display a "press any key to continue" message and wait for a keypress.
|
||||
- `bbpick [prompt]`: Select one of `NULL`-delimited multiple inputs and print it.
|
||||
- `bbtargets "$BBCMD" "$@"`: If `$BB` is not currently among `$@` (the
|
||||
selected files), this script prompts the user to ask whether they want to
|
||||
perform an action on the selected files, or on the cursor. The result is
|
||||
printed as `cursor` or `selected`.
|
||||
- `bbunscroll`: Print text to the screen *above* the cursor instead of below it.
