Keyboard Mode
When a cursor is active, left click on the CRSR indication to switch to keyboard mode. While KYBD is flashing, the
simulator will disable all inputs, including joystick inputs. To leave keyboard mode, right click anywhere on the
screen or press Escape.
Hardware such as a Stream Deck can use the H events KLN90B_LeftKeyboard_Toggle and KLN90B_RightKeyboard_Toggle
instead of the click. They turn the cursor on if it is off and switch that side to keyboard mode. Pressed again, they
leave keyboard mode and the cursor stays on.

few LVars are available for animations.
