Besides having the benefits of always having “A Programming Language” at your finger tips when needed, most (if not all) of the symbols can easily be created using the builtin (Windows 10 and Windows 11) Emoji-Keyboard.

Yeah, until about 2008 or so, you needed to have a proprietary font installed just to use Dyalog APL. Then they modernised and shifted towards Unicode characters. Made life a lot easier! But still need to install things on Winduhs to easily type them in using keyboard shortcuts! ⊂∩∪⊃⍨≥⍉⌽⍋⍒⍒⍱⍱∨∨∨∧*○⍳↓↑~
