Working with Rulers

Straight line with 'Shift' key

The easiest way to paint a straight line in Rebelle is to press the Shift key while using any drawing tool. Pressing Shift sets one end of the ruler. Manually set the other end, press the mouse button or a pen and naturally draw the line between these two points. 

The tool snaps to the vertical and horizontal position when in the proximity of the right angle - to disable this, hold the Shift + Ctrl keys.

To create lines, circles, ellipses or perspectives with more advanced options, activate the Ruler tool from the Edit menu or by hitting Shift + R.
