Motion, Editing and Mouse Emulation on The Far Thumb

The outer thumb button,Far in addition to functioning as the shift key has cursor movement chords on it. Pressing Far and Center together generates the key codes from the numeric keypad in place of the ones from the keyboard cursor and movement keys.

Microsoft Windows and X11R6 (a windowing system used in Linux, BSD Unix, Solaris and other flavors of Unix) both allow the numeric keypad to act as a mouse. This setting is usually found in your systems accessibility settings or control panel. By selecting mouse accessibility the spiffcorder can emulate a mouse in the same crude way a numeric keypad can.

Rather than duplicate the entire chart with the only change being the addition of the Center button, the column labled “Change Thumb to CF” indicates the keypad codes sent by the chorder when the the chord is made with the thumb pressing CF in place of only pressing F. The last column lists the mouse movement or mouse first button action that will be taken if you have set mouse emulation on your computer.1)
