Keyboard shortcuts

BIMopen has two kinds of shortcuts: keys, such as Ctrl+Z, which act at once, and typed shortcuts, such as WA, which you type letter by letter and confirm with Enter, like any command. Typed shortcuts are the same in every language.

On macOS, Cmd takes the place of Ctrl.

Keys

Key	What it does
`Ctrl`+`Z`	Undoes the last change
`Ctrl`+`Y` or `Ctrl`+`Shift`+`Z`	Redoes the change just undone
`Ctrl`+`S`	Saves the project; a project never saved asks for a file name
`Ctrl`+`P`	Opens Print
`Ctrl`+`A`	Selects the elements of the open plan's level, or of the whole model in a 3D view
`Del`	Deletes the selected elements, and the elements they host
`Home`	Fits the whole view in its window
`F1`	Opens the page of this manual about the open dialog, the ribbon button under the mouse or the active tool
`Esc`	Cancels the step in progress; pressed again, ends the tool; with no tool, clears the selection
`Enter`	Runs the line typed at the command line; confirms a value in the Properties palette
`Up` / `Down`	At the command line, the lines typed before
`Space`	While drawing walls, swaps the exterior and interior side; while placing a component or a detail component, rotates it
`Shift`	While drawing, keeps segments horizontal or vertical (or frees them, when Ortho is on); with a click or a window, takes elements out of the selection; while dragging, frees a joined wall or keeps the move horizontal or vertical
`Ctrl` + click	Adds an element to the selection; held when a drag starts, places a copy
`Tab` / `Shift`+`Tab`	Highlights the next (previous) element under the cursor, or a chain of joined walls and lines
`Ctrl`+`Left`	Selects again what was selected before
`Left` `Right` `Up` `Down`	Move the selection a small step; with `Shift`, ten steps

Ctrl+Z, Ctrl+Y, Ctrl+A, Del and Home act on the model only while you are not typing in a field: in a field they act on the text.

In a floor, roof, stair or railing sketch, Esc (or a double-click) also finishes the sketch when it has enough points.

In the Text Note dialog, Ctrl+Enter inserts the note and Esc cancels it.

Alt pressed and released, or F10, shows the ribbon's key tips. With no tool active and nothing typed, Enter repeats the last tool. After a click in the Project Browser, the arrow keys and Enter move in its tree.

Mouse

Wheel	Zoom at the cursor	Zoom
Middle button, drag	Pan	Pan; with `Shift`, orbit
Left button, drag	Selection window (left to right: inside; right to left: touching), or moves the selected elements	The same
Right button	Context menu; with a tool active, cancels the step	The same; dragging, orbit
Double-click	Finishes a sketch	–

Typed shortcuts

Type the letters while no field is being edited, then press Enter. Without arguments, a shortcut starts the tool or opens the dialog; with arguments, it runs the command at once (see Command line and MCP).

The commands with – have no short form, but their whole name works the same way. help lists every command and its short forms.

The zoom commands have typed shortcuts too: ZR zoom in region, ZO zoom out (2x), ZF zoom to fit, ZA zoom all to fit, ZS zoom sheet size, ZP previous pan/zoom. View ▸ Windows ▸ User Interface ▸ Keyboard Shortcuts gives any command shortcuts of your own (The interface).
