Disable Alt+drag as rectangle selection on Windows 10
Termius 5.1.0 or 5.3.0 beta
When holding down Alt key, the mouse cursor becomes a cross and allow selection of text within a rectangle region in the terminal tab. However, this gets in the way of MANY emacs key bindings that require holding down Ctrl and Alt at the same time
C-M-! Please allow users to disable this feature of Alt on Windows.
