Dyalog APL Keyboard Layouts
Should you wish to type them on a normal keyboard:
https://abrudz.github.io/lb/apl has a browser bookmarklet which adds an APL language bar to the top of any web page so you can type in any input box with backtick prefixes.
https://github.com/abrudz/Kbd has a Windows Input Method Editor (IME) that adds system-wide RightAlt+letter combos.

Ask HN: Do I need a special keyboard layout to learn array programming?
:d) https://github.com/abrudz/Kbd

APL has the highest percentage of trans programmers for the 2nd year in a row, according to Stack Overflow survey
I use setxkbmap -layout us,apl -variant ,dyalog -option grp:switch on Linux and https://github.com/abrudz/Kbd on Windows.

Ngn/k (free K implementation)
This might have been true a couple of years ago but it is totally untrue now.
I'm not sure why you couldn't use the student version of Dyalog? Sounds like it would have been fine. There are also many more FOSS implementations of array languages now, such as ngn/k and April. https://github.com/phantomics/april
'only available for Linux' - not true https://github.com/abrudz/Kbd/ and others (also different input modes like `w for ⍵)
'no community support' - on the contrary there is a big and helpful APL community https://aplwiki.com/wiki/Chat_rooms_and_forums that is (imo) more useful than stackoverflow
'Dynamic scoping...' - Dyalog's (and other APL's) dfns have lexical scope.
'The language is extremely terse' - is this meant to be a bad thing?
'The code tends to be very hacky' - maybe if you write bad code or try and write C in APL (it won't work)
- Use TAB entry style in Dyalog for Mac?

Learning APL
In general programming I like to use a keyboard layout which allows typing APL glyphs with Right Alt: https://github.com/abrudz/Kbd

Konna, my programming language
At first, I thought you were going to be talking about Kona which is another language. You may wish to consider a more unique name, though Kona isn't super well known.
-
Here's how 2 lines of APL code checked & fixed 1h of maths calculations on paper.
For anyone interested in using a language like APL that doesn't require special symbols, I'd recommend K. You can try it out using Kona.

Some thoughts on APLs (real or imagined) beauty, and the value of very concise languages (Twitter thread)
There are some open source implementations of J and K that you might enjoy.
