FreeCommander Forum

Does freecommander have the capability to override or modify shortcuts in other applications.

If you mean keyboard shortcuts in other applications then - no.

You can use HotkeyP to override or modify shortcuts in other applications, it's free and open source.

HotkeyP - keyboard/mouse/gamepad mapper (easy to use, lightweight, many features, e.g. macros, hide window, opacity, always on top, change wallpaper, magnifier, volume, mute, disable key - like CapsLock...)
