Controls

Draw

• Left click to draw.
• Shift + Left click to draw lines.
• Control + Shift + Left click to change the brush size. Drag left to shrink the size and right to increase it.
• R to unlink the pen and eraser sizes so each tool remembers its own. Press R again to relink them; the current tool's size wins. While unlinked, the eraser cursor shows a second inner ring.
• Save the current tool's size with Control + Shift + 1, all the way to Control + Shift + 9. Load a saved size by pressing Shift + 1, ... Shift + 9.
• Alt + Hover to select a different color.
• Control + Alt + Hover to select a different background color.
• E to toggle the eraser.
• T to toggle the temporary mode. Strokes aren't saved and erase themselves from their starting point shortly after pen-down, retracing the stroke at the speed it was drawn — the oldest ink disappears first. Useful for pointing at things during a presentation. The delay and decay speed can be tuned in Settings.json (tempDelaySeconds, tempDecaySpeed).

Camera

• Middle click to drag the camera.
• Scroll wheel to zoom.
• Control + Middle click to zoom. Drag up to zoom in and down to zoom out.
• Dot and Comma to rotate.
• Hold Space use the hyper zoom. Release to go back to the previous position.
• Save the current camera position with Control + 1, Control + 2, all the way to Control + 9.
• Load a saved camera position by pressing 1, 2, ... 9.
• Slot 0 is reserved for toggling back and forth between the current and previous position. You can also toggle using your mouse's extra buttons if you have them.
