Sure! I use my twiddler with my Android phone, and have no need for num, alt, or ctrl, nor do I need to right-click anything. Truly, I don't use the joystick mouse at all on my phone, but if I did need it for something, I could press on it to send a left click. The only modifier key that's useful for me is Shift.
With this in mind, I was hoping to remap those unused keys to Space, 1 and 43, which are common shortcuts I use while reviewing flashcards on the AnkiDroid app. The AnkiDroid app doesn't support customizable keyboard shortcuts, so it has to be those specific ones.
I want to be able to access those shortcuts easily while otherwise leaving TabSpace or Backspice enabled on my twiddler for typing practice. I don't want to have to futz with turning numlock on to make those numbers available, but that's an option I've considered if it's true that there's no way to remap num/alt/ctrl to 1/Space/43.
Does that help explain what I'm going for? Happy to provide any additional information.
By the way, the activation email I received when setting up my forum account had a link that involved an inaccessible IP address rather than forum.tekgear.com - Thankfully, I was able to figure out that I needed to remove the IP address and substitute the forum.tekgear.com URL. The same was true for the notification email I received for your reply: it points to http://10.188.20.66/t/can-i-remap-the-num-alt-ctrl-shift-keys-or-the-three-mouse-buttons/119/2, which I can't access. You might want to take a look at that!
