Keyboard and mouse

Press ? inside MOB³ for the built-in about:help page, which is the canonical key, mouse and form reference for the running build.

Key	Action
`j` / `k`	Scroll one line down / up
`Space` / `b`	Scroll one screen down / up
`Ctrl-D` / `Ctrl-U`	Scroll half a screen
`g` / `G`	Top / bottom of the page
`Tab` / `Shift-Tab`	Next / previous link
`Enter`	Follow the focused link, submit the focused field, or insert a newline in a textarea
`h` / `Left`	Back
`l` / `Right`	Forward
`r`	Reload
`R`	Toggle reader mode
`D`	Toggle dark mode
`o`	Open the URL prompt
`/`	Find in the page, or in the console HTML tab
`n` / `N`	Next / previous find match
`u`	Show the current URL in the footer
`H`	Session history
`?`	Help page
`!`	JavaScript console
`q` / `Ctrl-C`	Ask to confirm quitting (`y`/`Enter` quits; any other key cancels)
`Esc`	Stop loading, leave a field, clear a selection, or show the exit hint

URL prompt

o or clicking the URL bar opens the prompt prefilled with the current URL and selected. Typing replaces the selection; Backspace clears it first.

Key	Action
`Left` / `Right`	Move one character
`Home` / `End`	Start / end
`Ctrl-B` / `Ctrl-F`	Move one character
`Alt-B` / `Alt-F`	Move one word
`Ctrl-Left` / `Ctrl-Right`	Move one word
`Alt-Left` / `Alt-Right`	Move one word
`Backspace` / `Delete`	Delete around the caret
`Alt-Backspace` / `Ctrl-Backspace`	Delete the previous word or URL segment
`Ctrl-W`	Delete the previous word or URL segment
`Alt-D` / `Alt-Delete` / `Ctrl-Delete`	Delete the next word plus separators
`Ctrl-A`	Select all
`Ctrl-K`	Delete to the end
`Ctrl-U`	Clear
`Ctrl-C` / `Esc`	Close without navigating
`Enter`	Navigate

A mouse click places the caret. Shift+drag is left to the terminal for native selection. Input is resolved as a URL first, then through the -search fallback.

Find

/ opens the incremental find bar. Typing searches case-insensitively and highlights every match. Enter confirms and closes the bar; n/N then move between matches. Down/Up also move while the bar is open. Esc closes the bar but keeps highlights; a later Esc clears them.

The find bar supports the same word-editing keys as the URL prompt.

Forms

Click a text input or textarea to focus it. The focused field shows a block caret.

Key	Action
`Left` / `Right`	Move by character
`Home` / `End`	Start / end of line
`Up` / `Down`	Move between lines in a textarea
`Alt-B` / `Alt-F`	Move by word
`Alt/Ctrl+Backspace`, `Ctrl-W`	Delete the previous word
`Alt-D` / `Alt-Delete` / `Ctrl-Delete`	Delete the next word
`Backspace`	Delete backwards
`Delete`	Delete forwards
`Ctrl-U`	Clear
`Enter`	Submit (or insert a newline in a textarea)
`Esc`	Leave the field

Checkboxes and radios toggle on click. A <select> opens a popup; use Up/Down and Enter, or click an option. <select multiple> renders as a list box; clicking an option toggles it. A file input opens a notice that uploads are unsupported.

Mouse

Hover a link to show its target in the footer.
Drag to select page text; y copies it through OSC 52.
Click a link to follow it; a download link opens the curl popup instead.
Click the URL bar to open the prompt; click outside to close it.
Click in the prompt to move the caret.
Click ←, →, ⟳, ⌂, History, Bookmarks, Help or ⚙ in the toolbar.
Right click goes back; the mouse back/forward buttons navigate.
Click Dark:on/Dark:off, Reader:on/Reader:off or the >_ icon in the footer.
The wheel scrolls three lines; drag the right-edge scrollbar to jump.

Shift+mouse reports from the terminal are ignored so the terminal can keep a native selection over the URL. Terminal-native selection needs the terminal's Shift override.

Terminal support

MOB³ enables the kitty keyboard protocol in detected kitty, WezTerm, Ghostty and foot terminals. That makes Esc, modified keys, Shift-Tab and key releases reliable. Multiplexers (tmux, screen, zellij) are excluded because their forwarding is inconsistent.
