This is the Standard Menu. If you click the X on this Menu, then your standard MMO 1 through = Hotkeys will be inactive -- they are tied to this Menu and if you close it, the Hotkeys deactivate.
The first time you launch a team with ISBoxer 41, a box pops up explaining how you can move this menu (with Ctrl+Shift+Alt+G as OP mentioned) to place it over your standard Action Bars, e.g. in World of Warcraft. You don't "need" them, they are there as a visual indicator when you press your Hotkeys, and the bar is only 25% visible so that it shouldn't get in your way under normal use (placed over your Action Bar).
If you would not like the Standard Menu, then during the Quick Setup Wizard on the last page, at the bottom, you have the choice between this Menu (preferred) and simply using a Key Map (invisible, the old way). If you have already created a team with ISBoxer 41 with the Menus, and already have the Combat Key Map, then the Combat Key Map will be left as-is -- without the Hotkeys that were assigned to the Menu.
