Variants

ScrollLines(i64)

ScrollLogicalLines(i64)

J / K — jump forward or backward by one whole logical line, skipping any remaining wrap rows of the current line. Useful for long lines that wrap many screen rows.

PageDown

PageUp

HalfPageDown

HalfPageUp

Quit

Resize(u16, u16)

Refresh

ToggleLineNumbers

ToggleChop

ToggleFollow

SearchForward

/ — open the forward-search prompt.

SearchBackward

? — open the backward-search prompt.

NextMatch

n — repeat the last search in its original direction.

PreviousMatch

N — repeat the last search in the opposite direction.

OptionPrefix

- — option-toggle prefix: the next key chooses an option to flip (N → line numbers, S → chop, F → follow).

Reload

R — force-reload the source from disk now (only meaningful with --live; no-op for static file sources and append-streaming follow).

TogglePrettify

Shift-P — toggle pretty-printing on/off (cycles back to the last active mode if currently off).

SetPrettifyMode(PrettifyMode)

Set a specific prettify mode (issued by the -P<letter> sub-prefix after the user picks j/y/t/x/h/c).

RedetectPrettify

Re-run byte-based content detection and apply the result (-Pa).

Digit(u8)

A digit (0-9) was pressed. The app accumulates these into a numeric prefix that the next non-digit command consumes.

GotoLine

Jump to physical line N (1-indexed). Without a prefix, behaves as goto-top.

GotoRecord

Jump to record N (1-indexed). Without a prefix, behaves as goto-bottom (preserves the existing bare-G behavior).

GotoPercent

Jump to N percent through the file by bytes. Without a prefix, behaves as goto-top.

Cancel

Cancel any pending numeric prefix without firing a command.

MarkSet

First half of a set-mark sequence (the m key). The next keystroke names the mark.

MarkJump

First half of a jump-to-mark sequence (the ' key). The next keystroke names the mark.

CtrlXPrefix

First half of the Ctrl-X Ctrl-X jump-to-previous-position chord. The next keystroke must also be Ctrl-X.

JumpPrevious

Jump to the previous position (Ctrl-X Ctrl-X in less). Dispatched from the CtrlXPending mode intercept in app.rs.

Noop

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Command

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Command

fn eq(&self, other: &Command) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Command

impl StructuralPartialEq for Command
