I was looking to split my Debian desktop screen, tile my windows the way I want. Here is how I got it done.
Launch Windows Manager, click on Keyboard-Tab,
Scroll down via the 'Action' column to the "Tile Window" settings.
To set the "ShortCut setting", double click on each Action and Press your shortcut key-combination.
Window Manager(before)
Windows Manager (after)
Note: Control+Super+Left....where Super is the Windows-Key
Here is my desktop view: firefox on the left and chrome on the right
Thats all Folks
