[Feature Request]: better keyboard implementation

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

ok i see all your inputs are mouse or pad optimized but i think most nerds using **keyboard**

lets say i have this


so i must click on every single number write a number and MUST hit enter
very unconfortable ;)

so why not once click on a number write a number and lets say with arrow keys i can move to the next number with out hiting enter to confirm the number ...

maybe also set, if no numbers are allowed, I can't write any
maybe set also "coma" same as "point"

and if i use "ctrl"+mouse and mark some nodes than hit right mouse-button (where ever) i can only bypass one node, if i hit "crlr"+B it works for all ... so thats inconsistent on the other hand ...

### Proposed workflow

123
