Aplette is a slimmed down, 64-bit port of APL\11, dispensing with traditional features like the entire interactive environment with a built-in editor etc. Instead, the goal of is to isolate the core language to produce specialised utility along the lines of AWK and sed, only for array processing rather than text or stream processing.

Uniquely, Aplette removes APL's glyphs while basically retaining the way they are typed. This scheme, dubbed APL-touchtype, uses Shift as APL key and @ as overstrike key, so instead of (normally produced with APL+r) one would write R (Shift+r), and instead of (traditionally produced with APL+o ― overstruck with *) one would write O@*. This maps all APL glyphs to ASCII characters or sequences.
