Keybindings

The complete reference — the same content the editor shows on F1. ⌘ is the editor's primary modifier (Cmd on macOS, Ctrl elsewhere).

Views & session

Key	Action
⌘R	Toggle the source editor ↔ rendered reading view
Esc	Save & close (⇧Esc cancels / discards pending changes)
⌘↵	Toggle full-window width
⌘.	Section focus — dim all but the current paragraph (writing) / section (reading)
⌘T	Typewriter scrolling — hold the caret line steady while writing (persists)
⌘+ / ⌘- / ⌘0	Font size bigger / smaller / reset (persists)
⌘⇧→ / ⌘⇧← / ⌘⇧↓	Content column wider / narrower / reset (persists)
⌘J	Word-jump overlay (Easymotion-style two-key jump)
⌘P	Print
F1	Help

Writing (vim — source editor)

Key	Action
h j k l	Move left / down / up / right
w / b / e	Next word / previous word / word end
0 / $ · gg / G	Line start / end · document start / end
i a · I A · o O	Enter INSERT: before/after · line start/end · new line below/above
Esc	Back to NORMAL mode
x · dd · dw	Delete char · line · to next word
↵	Follow the link under the caret — web/mail in the browser, #heading jumps there (NORMAL mode)
go	Open another file — history is fuzzy-matched, paths complete per segment

Search (/) — both views

Key	Action
/	Search the document — matching lines ranked best-first (exact above fuzzy)
(type)	Live hit list; the view scrolls to preview the selected hit
⌃n / ⌃p · ↓ / ↑	Move the selection
Enter · Esc	Jump to the hit · cancel back to where you were
n / N	Next / previous hit (wraps; the query survives ⌘R)

Open-file dialog (go)

Key	Action
(type)	Fuzzy-match your history (files & their folders); a path (with / or ~) also completes the filesystem, segment by segment
⌃n / ⌃p · ↓ / ↑	Move the selection
Tab	Complete — extend to the common prefix, else adopt the selected row
Enter	Open the selected file (a directory descends into it); with no match, open the typed path as a new file
Esc	Cancel, back to the editor

See Opening files for how the matching works.

Reading view — navigate

Key	Action
h j k l · w b e · 0 $	Move a caret through the rendered text
gg / G	Document start / end
⌃d / ⌃u · ⌃f / ⌃b / Space	Half-page · full-page scroll
f	Focus reading mode — caret-lock at centre + a spotlight on the reading line, fading text by distance (persists)
gh	Headings overview — j/k preview live, Enter keeps, Esc restores your spot
gl	Links overview — same jump-list; Enter follows the picked link
↵	Follow the link under the caret — a .md opens in place, web/mail in the browser, #heading jumps there, anything else via the system handler
gb / ⌫	Back to the document the last link was followed from
go	Open another file (stays in the reading view)

Reading view — comments

Key	Action
v	Visual mode — extend a selection with the motions above
c	Comment the selection (or reveal/edit the comment under the caret)
]c / [c	Step to the next / previous comment
Enter · ⇧D	Reveal-edit · delete the active comment

Reading view — suggestions (track changes)

Key	Action
s	Suggest a change — replace the selection (empty = delete), or insert at the caret
]s / [s	Step to the next / previous suggestion
a / x	Accept / reject the suggestion under the caret and advance to the next
⇧A / ⇧X	Accept / reject all suggestions at once
gc	Changes overview — every change & comment, same live preview as gh
p	Clean preview — the prose with every suggestion accepted (source untouched)
