It could be the keyboard. I’m using the same keyboard that worked with the 3.0 build, but it’s a programmable Preonic from OLKB, so there may be room for shonkyness.
If I connect that keyboard to my Mac, the key combination that I’m using to create a tilde presents on the Mac as [SHIFT + tilde] (didn’t even know that was a thing!) - although on both the Mac and the TT it does display a tilde in text. That seems a little odd on the TT, no? If the tilde should directly display the live variables, then it shouldn’t ever print a tilde on the screen?
I’ll see if I can make the keyboard say something tilde-like that’s more acceptable to this build of TT
(and try with the original TT keyboard, too).
