0x4F Keyboard RightArrow 0x50 Keyboard LeftArrow 0x51 Keyboard DownArrow 0x52 Keyboard UpArrow sudo footswitch -k wCodes taken from: http://www.freebsddiary.org/APC/usb_hid_usages.php sudo ./footswitch -S '28'In this example the 28 produces a carriage return because 28 is 0x28 Keyboard Return (ENTER) sudo ./footswitch -S '52'In this example the 52 produces up arrow press because 2 is 0x52 Keyboard UpArrowBut this is only momentary. It is not like holding the UpArrow key depressed, so in a video game you will not keep moving forward but only just take a single step. sudo /chooser/footswitch -k upThe key name 'up' refers to the up arrow key 0x52 which in this example will act as a keyboard key so that it is _not_ momentary when the foot pedal remains depressed.THREE PEDAL SWITCH / MULTI PEDAL SWITCHFor a multi pedal switch you are not going to be able to program each pedal one at a time on individual command lines. All three must be programmed on a single command line. Each time the command is executed any unspecified pedals are simply set to null, therefore, even if you intend on only changing a single pedal it is still necessary to reinforce the same command on the other two. Here is an example command line: sudo footswitch -3 -k up -1 -k down -2 -k enter
