This is pretty cool: keyboard heatmaps of the most pressed keys in various
programming languages:

syntaxes
(I found this via @SansMouse on Twitter, which is pretty useful to follow,
if you're a keyboard jockey like I am).
Also, you can generate your own keyboard heatmap, given a representative

I plugged in my J utilities script, sans comments, and the result was
interesting. Some parts were unsurprising (dots and colons scored high),
but others weren't totally expected. For example, even without comments
(i.e. scoring only J code, not English), 'e' ranked pretty high. Also, my
paren keys were almost as "hot" as the ones in the Lisp heatmap. Though, I
suppose, my script shouldn't really be considered representative as J as a
language, so much as the ramblings of a tacit weirdo.
What script can/should we use to generate a heatmap for J, that fairly
represents the language as typically written? I'd like to share it back
with the maintainer of the comparative heatmaps page.

PS: One improvement I would like to see in the heatmap generator is
indications of the metakeys: I bet J would score a lot higher on SHIFT than
a lot of other languages.
