- move "fire starter" from SPACE-key to s-key - move "open property browser" from Shift-SPACE to Shift-Enter (Shift-Return) - implement PTT on SPACE/Shift-SPACE (with the other six SPACE/modifier combinations unused, apart from a popup) - add controls.ptt(v) wrapper function (v can be 1 or 2 for on, and 0 for off) Easter-Egg: - pressing the t-key for at least one second resets the warp delta. This is an experimental feature that most people won't notice. It's meant for investigating if suchlike "unorthodox" key use is acceptable. While modifier-keys are the norm on computer keyboards, modifier-times aren't, although we are used to them from other devices, such as alarm clocks etc.) May later get removed without warning.
