If you’re using MacOS as your client and you’re working with GemTools remotely through X11, you may find that it gets confusing having to switch from Mac key shortcuts such as Cmd-b, Cmd-n, Cmd-m… to the subtly different Unix key bindings of Ctrl-b, Ctrl-n, Ctrl-m…
The solution is to create a key mapping file;
~/.Xmodmap to ensure that CMD key functions on the remote GemTools as it does on the local version.
remove Mod2 = Meta_L Meta_R keysym Meta_L = Control_L keysym Control_L = Meta_L keysym Meta_R = Control_R keysym Control_R = Meta_R add Mod2 = Meta_L Meta_R add Control = Control_L Control_R
You also need to change the preferences in the X11 mac app. Ensure the following are disabled:
- ‘Follow system keyboard layout’.
- ‘Enable key equivalents under X11’.

You’ll have to logout of your remote X session before the key mapping becomes active.
