Keyboard shortcuts

Press ? at any time to see the list inside the app (outside a text field).

On macOS, Cmd works wherever this page says Ctrl. The app’s own labels always say Ctrl.

General

Keys	Action
Ctrl+K	Command palette
Ctrl+O	Open FCS files
Ctrl+S	Save workspace
Ctrl+Shift+O	Open workspace
?	Keyboard shortcuts
Escape	Close dialog / exit drill-down / cancel a drawing

Ctrl+K is the one worth learning first — it reaches anything you can name without hunting through menus. In the palette, the arrow keys move, Enter runs the command and Escape closes it.

Gates

Keys	Action
Ctrl+Z	Undo gate change
Ctrl+Y or Ctrl+Shift+Z	Redo gate change
Delete or Backspace	Delete selected gate — no confirmation; undo restores it
Double-click gate	Drill down into gate
Escape	Navigate up from drill-down
Double-click a gate’s name in the gate list	Rename gate (Enter keeps, Escape cancels)

Escape goes up from a drill-down only when the layout shows a single plot; with several plots, use the Go up button above the plot.

To abandon a gate part-way through drawing, press Escape or click the Navigate tool (the cursor) in the gating toolbar. While you are drawing, Escape cancels the drawing rather than going up from a drill-down; in a text field or an open dialog it does neither.

Plot navigation

On scatter, density, contour and zebra plots:

Keys	Action
Scroll wheel	Zoom in / out
Click and drag	Pan (in navigate mode)
Double-click empty space	Reset zoom

While drawing a polygon, a double-click closes the shape instead.

File management

Keys	Action
Ctrl+Click	Select several files
Double-click file	Rename file (Enter keeps, Escape cancels)

Selecting several files offers Apply Gates, Apply Comp and Close for the selection. See The interface.
