When a command is still unfamiliar, a wall sheet keeps it in sight instead of asking working memory to hold it. [[Externalizing thought builds a cognitive scaffold for solving complex problems]] explains why the paper becomes part of the workspace. Each glance rehearses the link between an intention and a shortcut. Repetition turns that lookup into muscle memory, and the reference slowly disappears into the room. [[Deep work shields attention]]. A visible reference protects it by leaving the current screen untouched. [[Mobile preview without breaking flow]] and [[Preview panes preserve reading flow]] follow the same rule: put supporting context beside the work instead of in its place. I make these sheets for tools I use often enough that their keyboard models should become automatic. ## References Herdr keyboard wall sheet — Pane focus, tabs, layout, workspaces, and session shortcuts for [[Herdr]].
