Keyboard Shortcuts

Press F1, or go to Help → Shortcuts in the menu bar, to open this same reference inside the app at any time.

File

Shortcut	Action
`Ctrl+S`	Save
`Ctrl+Shift+S`	Save As
`Ctrl+O`	Open

Edit

Shortcut	Action
`Ctrl+Z`	Undo
`Ctrl+Y` / `Ctrl+Shift+Z`	Redo
`Delete`	Delete the selected object/ROI

Delete opens the same confirmation dialog as the trash-can button in the Object List panel’s footer, rather than deleting immediately, and only does anything while an object is actually selected.

Pipeline

Shortcut	Action
`F5`	Refresh the preview

Re-runs the pipeline preview once - the same as the toolbar’s “eye” button or the Pipelines panel’s Preview action - a single dry-run, distinct from toggling Auto Preview on or off.

Canvas Tools

Shortcut	Action
`M` / `Escape`	Move
`S`	Select
`K`	Paint marker
`R`	Paint rectangle
`O`	Paint oval
`P`	Paint polygon
`#`	Show/Hide objects

These are unmodified single-letter mnemonics, so they only fire when the viewport (not a text field) has keyboard focus - typing into a search box or name field types the letter normally instead of switching tools.

Shortcut	Action
`Ctrl+1`	Images tab
`Ctrl+2`	Meta tab
`Ctrl+3`	Pipelines tab
`Ctrl+4`	Results tab
`Ctrl+F`	Jump to the image search field

Ctrl+1..4 follows the same convention as switching between browser tabs. Ctrl+F switches to the Images tab first if it isn’t already active, then focuses its search field.

Dialogs

Shortcut	Action
`Escape`	Close the open dialog
`F1`	Show this help

Escape is deliberately disabled while a pipeline analysis or preview render is actively running: since cancelling a background job only requests cancellation rather than closing the dialog immediately, a reflexive Escape there would look like it silently did nothing while killing a possibly multi-minute run. Use the dialog’s own Cancel button instead - the distinction is intentional.
