Keyboard Shortcuts

⌘ is Command. A couple of tab-strip shortcuts deliberately use a literal Control instead — see the note below the table.

File

Shortcut	Action
`⌘N`	New tab
`⌘O`	Open…
`⌘S`	Save
`⌘⇧S`	Save As…
`⌘W`	Close tab
`⌘,`	Preferences
`⌘Q`	Quit

Edit

Shortcut	Action
`⌘Z`	Undo
`⌘⇧Z`	Redo
`⌘X`	Cut
`⌘C`	Copy
`⌘V`	Paste
`⌘A`	Select All
`⌘F`	Find
`⌘G`	Go to Line
`⌘/`	Toggle line comment

Tabs

Shortcut	Action
`⌘T`	New tab (macOS convention)
`Ctrl+Tab`	Next tab
`Ctrl+Shift+Tab`	Previous tab

Ctrl+Tab/Ctrl+Shift+Tab use a literal Control key on every platform, including macOS — ⌘Tab is reserved by the OS for the app switcher, so Nib follows the same convention as browsers and VS Code for cycling through tabs.

View / Zoom

Shortcut	Action
`⌘=`	Zoom in (current tab)
`⌘−`	Zoom out (current tab)
`⌘0`	Reset zoom (current tab)

Find bar

Shortcut	Action
`Enter` (in Find field)	Jump to next match
`Enter` (in Replace field)	Replace current match
`Escape`	Close the find bar
