I am a long time emacs user learning Vim. Emacs lets me navigate in the mini-buffer (where I issue commands like C-x C-s) using the same navigation keyboard shortcuts as in any
Some from the Vim help:
CTRL-B or
cursor to beginning of command-line
CTRL-E or
cursor to end of command-line
CTRL-H
Delete the character in front of the cursor (see |:fixdel| if
your key does not do what you want).
Delete the character under the cursor (at end of line:
character before the cursor).
CTRL-W Delete the |word| before the cursor. This depends on the
'iskeyword' option.
CTRL-U Remove all characters between the cursor position and
the beginning of the line.
