Every action in Meiji Sampler is a keypress. This page documents the main shortcut surfaces by context.

​
Vim-style navigation

All arrow key navigation supports h/j/k/l as alternatives:
Vim keyArrow equivalent
hLeft
jDown
kUp
lRight
These work everywhere arrow keys work: browser, pads, loops, scenes, mixer, editors, modals, and settings. Some contexts previously used h, j, k, or l for other actions — those have moved to shifted variants. See Upgrade And Migration Notes for details.

​

Higher transient snap sensitivity shows more ghost markers and accepts softer hits. Lower sensitivity keeps the snap points stricter. The snapping workflow is inspired by Cool Edit Pro’s bracket-key playhead movement, while the marker sensitivity model is inspired by ReCycle-style transient slicing. See Chopping And Slicing for the workflow guide.
