The Main Window and Navigation

The Main Window and Navigation

The main window shows the current section's image with its traces drawn on top (the field). Floating overlays sit on top of the field: the tool palette (the column of mode buttons, top-right by default), the trace palette (the row of preset traces, bottom-center), section-increment buttons, brightness/contrast sliders, and a scale bar. Each overlay group can be dragged to reposition it, and View ▸ Reset palette position restores the defaults.

Moving between sections

• Page Up / Page Down — next / previous section.
• Mouse wheel over the field — scroll up for the next section, down for the previous (works in any tool mode).
• Go to section (Ctrl+G) — jump to a section number.
• The section-increment buttons (▲/▼) in the corner do the same as PgUp/PgDown (handy on tablets).

Panning and zooming (in any tool)

• Middle-click and drag — pan the view.
• Ctrl + mouse wheel — zoom about the cursor.
• Home — fit the view to the image. View ▸ View magnification… sets an exact zoom (useful for consistent figure scale).

The dedicated Pan/Zoom tool (below) is an alternative when a middle mouse button isn't available.

Brightness and contrast

Adjust the current section with the corner sliders, or with the keyboard: brightness = / -, contrast ] / [ (also under Edit ▸ Brightness/contrast). Named brightness/contrast profiles are available under Series ▸ Brightness/contrast profiles….

Showing and hiding interface elements

Under View ▸ Palette ▸ Visibility you can independently toggle the trace palette, the section-increment buttons, the brightness/contrast sliders, and the scale bar. View ▸ Left handed swaps the tracing-pencil cursor side.

Theme

View ▸ Change theme offers Default and Dark. (The theme can also be set under Series ▸ Options.)
