Implement tab input method in RIDE

[PixelSergey]

Describe the issue you are having

TryAPL and other online APL editors allow users to input glyphs using the tab input method.
Examples:

• ← can be inputted using the key combination < - TAB
• ≡ can be inputted using the key combinatoin = = TAB
• Etc.

This is a very useful feature, since many glyphs in RIDE do not have a prefix method of inputting and must be selected with a mouse using the language bar.

Did you connect to an already running interpreter or start the interpreter from Ride?

Start the interpreter from RIDE / irrelevant

How do you reproduce the issue?

Attempt to do a tab input key combination as described above

@PixelSergey Which glyphs in RIDE do not have a prefix method of inputting and must be selected with a mouse using the language bar?

[PixelSergey]

@abrudz Left tack, right tack, tally, grade up, atop, over, variant, quad diamond, I-beam, right arrow (with a keyboard that has deadkeys), zilde (with a keyboard that has deadkeys)

[abrudz]

Aren't e.g. grade up prefix followed by Shift+4 and over prefix followed by Shift+o?

[PixelSergey]

Aren't e.g. grade up prefix followed by Shift+4 and over prefix followed by Shift+o?

Nope, neither work (xkbmap FI)

Over doesn't have a prefix entry, and the entry for grade up says:

GRADE UP (⍋)
Keyboard: §⊢

which is a little silly, I don't have a right tack key on my keyboard 😂

[abrudz]

Over missing is probably due to an old version. Try if prefix followed by AltGr+4

[PixelSergey]

Nope, doesn't work. AltGr+4 is $

[abrudz]

Yes, and I expected prefix, $ to give ⍋

[PixelSergey]

Yes, and I expected prefix, $ to give ⍋

Nope, just prints out the literal characters
