Shortcuts
The defaults, and where to change them
Here is a list of the default keyboard and mouse shortcuts in Weasis. The shortcuts are divided into different categories for better understanding.
Note
Most keyboard shortcuts can be customized since v4.7.0 in Preferences > General > Keyboard Shortcuts. This page documents the default configuration. To get the current configuration (including any customizations), use Help > Keyboard Shortcuts (this page is internationalized). Every tool of the Draw & Measure palettes, including the tools added by plugins, has its own entry there since v4.8.0; most have no key by default.

Tips and Tricks
Window / Level Adjustment
- Move the mouse horizontally to the right to increase the window width (reduce the perceived contrast).
- Move the mouse vertically upwards to lower the window center (increase the perceived brightness).
Tip: Use Preferences to reverse the direction of level adjustments.
Drawing a Segment
You can draw a segment in two ways:
- Click + Drag: Click, drag to draw, then release.
- Click > Release > Drag: Click to start, release, drag to draw, and release again.
