Hi There's no doubt that menuitem works, but some of the shortcuts is disabled, being used by the PsPad editor itself, e.g. the F1 shortcut.
Open your keymaps.ini file, and see what already is used. If you have installed PsPad properly, you can find it in C:\Users\ <YourUserName> \AppData\Roaming\PSpad -- Sincerely J.
