• "GreenOneShot" = dword:0
• "MultimapTimeout" = dword:258
When you press the Orange key or Green key, a timer
starts and will turn Orange or Green mode off after three
seconds. To force Orange or Green mode to stay active after the
timer has expired (which is also called “locking” the mode) you
must set *ObeyClear to 0.
When you press a key in Orange or Green mode, the orange or
green function for that key is produced and Orange or Green
mode is turned off. To force Orange or Green mode to stay active
after a key has been pressed (which is also called “locking” the
mode) you must set *OneShot to 0.
Creating Multiple Key Definitions
In the case of multiple key definitions, the first byte is the
number of possible keys (in words) that the physical key can cycle
between. The second byte must be 0x80 (this is what makes it a
multi-key definition). The values following should be two bytes
for each possible key.
Multiple key definitions can also be used for FkeyCode and
FkeyMeta mappings. In multi-key mode, only one VK code can
be emitted by the key.
MultimapTimeout is the number of milliseconds you have to
press the key again before the current selection is emitted. The
default is 258, which equals 600ms (0.6 seconds).
To understand MultimapTimeout, consider the numeric keypad.
When you press the Green
key and the 2 key, you have
selected the “a” character. You have 0.6 seconds to press the 2 key
again for “b.” If you do not press a key within 0.6 seconds, the “a”
is emitted. If you press another key within 0.6 seconds, the
timeout is cancelled, the “a” is emitted, and you have 0.6 seconds
to press the second key again to select a different letter.
Note: For a description of MultimapTimeout, see the next
section, “Creating Multiple Key Definitions.”
