Keyboard Shortcuts

Keyboard Shortcuts

mbr provides vim-style keyboard shortcuts for efficient navigation. Press ? at any time to view an in-app help overlay.

KeyAction
j / kScroll down / up (one line)
Ctrl+d / Ctrl+uHalf page down / up
Ctrl+f / Ctrl+bFull page down / up (Ctrl+f is macOS-only — see note below)
g gGo to top of page
GGo to bottom of page
H / LPrevious / next sibling page
Ctrl+o / Ctrl+iHistory back / forward

Note on Ctrl+f: full-page-down is bound on macOS only, where Cmd+F is the find key. On Windows and Linux Ctrl+F is left alone so it reaches find-in-page — the browser’s own in server and static modes, mbr’s in GUI mode. Use Ctrl+b, Space or PageDown to page forward there.

Panels

KeyAction
/Open search
- or F2Open file browser
=Open media browser
Ctrl+gToggle info panel
tOpen the task browser (server and GUI modes only)
eOpen the editor for the current file (when editing is enabled)
rAdd a review note, anchored to the selection (server and GUI modes only)
ROpen the review panel (server and GUI modes only)
EscClose current panel

Quick Navigation (Fuzzy Nav)

KeyAction
fOpen links out (outbound links from current page)
FOpen links in (backlinks to current page)
TOpen table of contents (headings)

Search Panel (when open)

KeyAction
Ctrl+n / Ctrl+pNavigate results down / up
/ Navigate results
EnterOpen selected result
Ctrl+d / Ctrl+uScroll results half page
EscClose search

File Browser (when open)

KeyAction
j / k / / Navigate tree
Ctrl+n / Ctrl+pNavigate tree
hCollapse folder / go to parent
l or EnterExpand folder / open file
oOpen in new tab
Ctrl+d / Ctrl+uScroll panel half page
EscClose browser

Task Browser (when open)

The task browser (t) is a live view of the tasks in your markdown, so it exists in server and GUI modes only — a static build has no files to re-read. Disable it with --no-tasks. See Task Browser for the full guide.

KeyAction
Ctrl+n / Ctrl+pNavigate tasks and headings
/ Navigate tasks and headings
/ Collapse / expand the focused group
EnterOpen the focused task in its file, or toggle the focused heading
SpaceComplete / reopen the focused task (when editing is enabled)
xCancel / reopen the focused task (when editing is enabled)
TabSwitch between the folder pane and the results pane
Ctrl+d / Ctrl+uScroll the active pane half a page
Ctrl+f / Ctrl+bScroll the active pane a full page
EscClose the filter options, then the panel

The filter field keeps focus the whole time, so Space, x, and reach it until you move onto a task with the arrow keys — and typing in the field hands them back. Filtering for “buy milk” therefore works as you would expect.

Review Notes (when open)

Review notes (r to add one, R for the list) anchor to the data-mbr-line source lines the renderer emits, which a static build never emits — so the feature exists in server and GUI modes only. Disable it with --no-review. See Review Notes for the full guide.

KeyAction
Ctrl+n / Ctrl+pNavigate file headings and notes
/ Navigate file headings and notes
EnterOpen the focused note (scrolls when it is on this page, navigates otherwise)
eEdit the focused note
dDelete the focused note — press d again to confirm
cCopy the whole review as markdown
Ctrl+d / Ctrl+uScroll the list half a page
Ctrl+f / Ctrl+bScroll the list a full page
EscBack out of a clear-all confirmation, then close the edit form, then the panel

d arms and a second d fires, because nothing in the feature has an undo. The bare letters yield to whatever you are typing in: while the edit form is open, or focus is in a text field, e, d and c are ordinary characters.

Clear all — which deletes every note in every file — is a header button with its own confirmation and has deliberately no shortcut: every key above affects a single note, and a whole-review delete should not be one keystroke away from a typo.

Task Checkboxes (in a page)

With editing enabled, the checkboxes in a rendered page are clickable.

ActionResult
Left clickComplete / reopen the task
Right clickCancel / reopen the task

Fuzzy Nav Modal (when open)

KeyAction
TabSwitch between tabs (Links Out / Links In / ToC)
Shift+TabSwitch tabs in reverse
Ctrl+n / Ctrl+pNavigate results
/ Navigate results
EnterOpen selected item
EscClose modal

Find in Page (GUI mode)

GUI mode (mbr -g) has no browser chrome, so it ships its own find bar, driven from the native Edit menu. In server and static modes this bar is not present at all and your browser’s built-in find works as usual.

ActionmacOSWindows/Linux
Open find barCmd+FCtrl+F
Find nextCmd+GF3
Find previousShift+Cmd+GShift+F3
Find next / previous (bar focused)Enter / Shift+EnterEnter / Shift+Enter
Close find barEscEsc

F3 is used off macOS because Ctrl+G is already the info panel toggle. On macOS the info panel keeps Ctrl+G, and Cmd+G belongs to find-next as the platform expects. Reloading the page (including live reload) closes the bar and clears its highlights.

macOS GUI Mode

In GUI mode (mbr -g), standard macOS shortcuts are available:

KeyAction
Cmd+OOpen folder or file
Cmd+RReload page
Cmd+[History back
Cmd+]History forward
Cmd+FFind in page
Cmd+G / Shift+Cmd+GFind next / previous
Cmd+Option+IToggle developer tools
Cmd+WClose window
Cmd+QQuit application

Standard Edit menu shortcuts (Cut, Copy, Paste, Undo, Redo, Select All) work as expected in text fields.

Linux GUI Mode

In GUI mode (mbr -g) on Linux the menu bar is hidden by default — it is a GtkMenuBar drawn inside the window, which no modern GTK application of this shape shows, and a tiling Wayland compositor has no global menu to move it to.

Every shortcut below works whether or not the bar is on screen. GTK will not activate an accelerator belonging to a hidden menu item, so mbr answers these keys itself while the bar is hidden and hands them back to GTK when it is shown — one route at a time, so a key never fires twice.

KeyAction
F10Show / hide the menu bar
Ctrl+OOpen folder or file
Ctrl+RReload page
Ctrl+Shift+PPrint
Ctrl+FFind in page
F3 / Shift+F3Find next / previous
Alt+← / Alt+→History back / forward
Ctrl+Shift+IToggle developer tools
Ctrl+W / Ctrl+QQuit

Editing keys (Ctrl+C, Ctrl+V, Ctrl+X, Ctrl+Z, Ctrl+A) are handled by WebKit inside the page and never depended on the menu bar.

Print is Ctrl+Shift+P, not Ctrl+P: plain Ctrl+P is “previous item” in mbr’s own lists (paired with Ctrl+N), and a native accelerator would take it from the page.

Set gui_menu_bar to "always" to start with the bar visible, or "never" to turn it off for good (F10 then does nothing).

Because mbr claims F10, GTK’s own “F10 moves keyboard focus into the menu bar” behaviour is off in this window. The bar is still usable with the pointer, and every item has its own accelerator.
