Huh. It looks like most people are using macros for "doing things". I'm using them mostly for "typing things."
I'm using cap lock (whose original purpose is nearly useless to me) as a modifier key to invoke a macro layer. So CL should be read as "holding down that key."
CL- most of the alphabetic keys --> Greek alphabet
CL- numeric keys --> ∀ ∃ ∄ ∋ ∌ ∧∨∩∪ ∅
CL-much of spacing punctuation --> combining accents. (, for cedilla, ` for grave, ' for acute, " for umlaut, - and / for different kinds of strikeout, _ for underline, = for double underscore, . for dot-below, ^ for circumflex etc, Basically whatever combining accent they sorta look like, plus some arbitrary mappings like @, &, * for circle-above, overbar, and breve).
CL-! is ¡ and CL-? is ¿, CL-< is « and CL-> is » (Spanish inverted punctuation and french quotation marks)
CL-numpad * / + - for × ÷ ± ≅
CL-numpad 2, 3, 4 for √, ∛, ∜ (roots)
CL-numpad 8 for ∞ (infinity)
several others but you should see a geeky pattern emerging....
