Ctrl-U (see ":help c_CTRL-U") removes everything left of the cursor (but
not the colon) on the command-line.
When you type a count, then hit the colon, Vim will automatically insert
a range of (count) lines starting at the cursor line. For instance 5:
becomes :.,.+4
When you hit the colon key in Visual mode, Vim will get out of Visual
but it will insert the range '<,'> meaning "all lines of the former
Visual area". (Ex-command ranges are always linewise.)
In both these cases, a mapping whose {rhs} starts with :<C-U> will
insert a range as a reselt of the colon, then immediately remove the range.
Best regards,
Tony.
