Hotkeys Page (Settings dialog box)
Allows you to define alternative key combinations for the hot keys <Alt> <F1> to <Alt> <F12>, as these can be used by X Windows.
By default, they are generated by <Alt> <Ctrl> <F1> to <Alt> <Ctrl> <F12>, but you can change the definitions by selecting alternative keys from the pop-up menus.
Any <Alt> key combinations not used by your X Window manager can be used as normal within your Citrix session.
In addition, the key combination <Ctrl> <Alt> <Enter> can be used to produce the PC key combination <Ctrl> <Alt> <Delete>.
