Touch bar on Macbook inserts invisible characters?

W. Craig Carter, MIT

On a Mac with a touchbar, if my finger slips and hits any of F2-F12, an invisible character .00 is entered. It would be ok if I could see the character and find the error. But, I can't see it as it is, ummm, invisible. (I've been copying and pasting every input to a vi buffer to look for the .00, or showing the cell contents with Shift-Control-E)

Is there any way to make .00 show up as a visible character? Or better yet, map F2-12 to something other than entering a visible character?

I've tried adding to KeyEventsTranslations.tr:

Item[KeyEvent["F3"], SelectionHelpDialog[False]]

etc

Item[KeyEvent["F12"], SelectionHelpDialog[False]]

Mathematica 12 doesn't show the touch bar in ControllerState[].

I'm completely stuck. My only solution so far is to attach an external keyboard.

Craig,

Go to SystemPreferences->Keyboard->shortcuts. Click on App Shortcuts and click on +. In the dialog you choose "Mathematica" and assign the function keys you hit to an innocuous function or keystroke. For example you can set F2->Evaluate Cell. Now if you hit the function key by mistake it will evaluate a cell and not add any keystrokes.

I also use this to assign menu items without any shortcuts to my own shortcuts. For example, there is no shortcut for making a cell Evaluatable -- so I made one.
