User Interface
The user interface consists of a single ruler that can be displayed either horizontally or vertically.
Figure 1: The ruler user interface.
Hold down the primary mouse button on the ruler to drag it around the screen. Click the secondary mouse button on the ruler to open a context menu called the Ruler Menu.
If the mouse cursor moves beyond the right or bottom edge of the ruler, it will automatically extend. The ruler will stay extended if:
- the cursor is frozen, or
- a Guideline is set beyond the default size.
Guidelines are explained in more detail in the Guidelines section.
The primary mouse button is determined by the Select your primary button option in the Mouse Settings in Microsoft Windows.
Rotating the ruler
The ruler can be rotated using the Ctrl + Shift + Alt + R key combination or by the Ruler Menu → Rotate menu item.
This is assignable to a mouse button click via the Rotate function.
It is not possible to have both a vertical and a horizontal ruler displayed at the same time.
When rotating the ruler, the axis changes but any Guidelines are kept in the same position.
Flipping the ruler
Figure 2: The horizontal ruler flipped in both directions.
The hatch marks on the ruler can be flipped to be displayed on the opposite side of the ruler.
This is done by pressing the Ctrl + Shift + Alt + E key combination or by the Ruler Menu → Flip Direction menu item.
This is assignable to a mouse button click via the Flip function.
Shifting to the cursor
The ruler can be shifted to the cursor position using the Ctrl + Shift + Alt + S key combination.
This will shift the ruler along its current axis and position the 0 on the ruler to the cursor position.
Holding down the key will continuously shift the ruler to the cursor position.
Freezing the Cursor
You can freeze the cursor on the ruler so that it does not move with the mouse.
This is done by pressing the Ctrl + Shift + Alt + F key combination.
