Subject: gitk: Add a help menu item to display key bindings
X-Git-Tag: v1.3.0-rc3~7^2~5
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=4e95e1f738720e2f768098f73e76109c15a4e1ff;p=git.git

gitk: Add a help menu item to display key bindings

Suggested by Paul Schulz.  I made it a separate entry under the Help
menu rather than putting it in the About box, though.
