Space key and move tool

In many design tools, you can move the canvas while working by using the spacebar. Here's how it works:

Activate the Move Tool (temporarily):

While using any tool (e.g., the cursor, text tool, or shape tool), press and hold the spacebar. This temporarily switches your cursor to the "Hand" tool for moving the canvas.
Drag the Canvas:

With the spacebar pressed, click and drag on the canvas with the left mouse button. The canvas will move in the direction you drag.
Release the Spacebar:

Once you release the spacebar, you’ll automatically return to the tool you were using before.

The issue names no files, tests, or entry points. Start by locating the canvas interaction and tool-selection code, then trace how keyboard and pointer events are handled. Done means holding Space temporarily enables canvas dragging and releasing it restores the previously selected tool.
