I only ever use hotkey:
Win+G is the default AFAIK
Right-click the systray icon >Hotkeys >etc.
Win+G will show a grid, you can move on to the next grid(s) by pressing the "n" key
Right-click the Systray icon >Options >Show numbers on grid
if that's selected the relevant numbers will select the relevant grids
Hope that makes sense.
PS there is a help text file
from the help file
4 - Keyboard Hotkeys
The following hotkeys can be configured through the tray menu ->
4.1 - The command mode
By pressing WIN+G (g for Grid/GridMove), you'll make GridMove go into
Command mode. The grid will come up, and you'll have a small box in
the middle of the screen. GridMove will now wait for you to press
something. If you press esc, it'll quit Command mode.
Command mode is very useful for moving a window somewhere real fast,
or for cicling grids using the keyboard.
If you press a number, the window will be moved to the corresponding
If you press N GridMove will switch to the next grid on its list.
If you press M, the window's maximize state will be toggled.
If you press 0, the window will be minimized.
If you press R, the script will be reloaded.
4.2 - FastMove
FastMove is a faster alternative to Command mode.
I dont know what "FastMove" is...
