Hotkeys

You can not only use the mouse to operate the program, but also these keyboad keys (from left to right):

Settings "T" (toolbox)
Text 1 "1" or "Numeric Keypad 1"
Text 2 "2" or "Numeric Keypad 2"
Text 3 "3" or "Numeric Keypad 3"
Text 4 "4" or "Numeric Keypad 4"
Text 5 "5" or "Numeric Keypad 5"
Reset "R" or "Esc"
Start / Stop "S"
Scrolling Speed "Cursor Left / Right" or "Page Up / Down" (or mouse wheel)
Full Screen "F"

These hotkeys work only when the program window has the focus, they do not work globally.

For global hotkeys that work also when the program window does not have the focus, see the settings dialog:
