Might be a very silly question to many folks out there, but I'm dense!
Applying predefined layouts:
C-a M-1 switch to even-horizontal layout C-a M-2 switch to even-vertical layout C-a M-3 switch to main-horizontal layout C-a M-4 switch to main-vertical layout C-a M-5 switch to tiled layout C-a space switch to the next layout
What is M? If it's just shift+m then please take away my neckbeard right now. I thought it might be alt + key but that doesn't seem to be it.
