Copy, paste, select all and delete

The four verbs stand in the Edit menu, each with its key, the same in every view:

• Copy, Ctrl+C (⌘C on a Mac): remembers what is selected in the project in hand. A toast says how many elements were copied and how to paste them.
• Paste, Ctrl+V: hands the copy to the Move tool of the view in hand, the plan's or the 3D's. The first click picks the anchor point on the copy, the second where it lands, and the copy is made at that second click, exactly as a copy with the Move tool would. A face pastes its hole, a component pastes another copy of the same component. Escape, or another tool, cancels.
• Select all, Ctrl+A: takes everything the view in hand can select.
• Delete, Delete or Backspace: takes the selection out of the project. The key deletes while the Select tool is in hand; with a drawing tool in hand, it is left to that tool.

The right-click menu carries them too: over a selection, Copy, Paste, Properties and Frame selection; over empty space, Paste, Select all and Frame everything. Each item is greyed when it cannot run, its hover saying why.

While an editor of its own is open, the tile editor or the sketch editor, the four verbs work inside it: Select all takes its lines, Delete its selection. Copy and Paste, which work on the project, are refused there, with the way back through the editor's own Done or Cancel.

• Repeating a wall, a window or a piece of furniture elsewhere, from a precise point.
• Copying a set of elements from one place of the plan to another.
• Selecting everything in a view to move it or to look at it.
• Clearing a selection out of the project.

Copy and Select all write nothing: the clipboard and the selection belong to the session. Paste writes the copies, one change that one Ctrl+Z takes back. Delete writes the project without what was deleted, keeping every other element's references right, one change too.
