I just realized that because each of the 8 jumps advertises itself as a unique Bluetooth device with it’s own BT ID, I can pair my TextBlade to the same device, such as my laptop, more than once. For example I can paire once on Jump slot 3 (JS3), and a second time on JS4.
I can set JS3 to be a normal textblade, and JS4 to be an extreme textblade with a totally different keyboard mapping optimized for one particular use. For instance I can replace the whole left blade with spreadsheet navigation and keyboard shortcuts and the whole right blade with a numerical pad and operators. When I want to type regular I can just jump back and forth between JS3 and JS4.
I can imagine people using this for other types of apps or usage also.
