I concede that very few people bother to learn the sequence or create a keybinding to symbols used at school. You can copy/paste if you only need it rarely, or use a software symbol selector (its icon in Word and Sheets is literally Ω). However, every keyboard that has a searchable emoji picker should also index the rest of Unicode in my opinion.
Custom keybindings I use the most are (in no particular order) πµΩαβγΔΣσ²³±√∞≤≥≠∈⋮⌀∙█⚠☢☣♥⚙✔✖❗←↑→↓·–ẞ, nbsp and hair space. There is also ☃ (Shift+AltGr+8) as an XKCD reference.
