usage

for the most part, hexapoda works similarly to Helix, but there are a few big differences:

• hexapoda uses ijkl for cursor movement by default. if you prefer the Obviously Worse hjkl, you can use this config
• to repeat an action a certain number of times, hexapoda uses the repeat action, bound to * by default. instead of entering a number of times to repeat, repeat uses the primary register, which allows repeating based on a value from the opened file
  • the showcase above uses this by selecting the word at 0x4 and yanking, then going to 0xc and selecting that number of words with v*e
