Mouse commands and conventions

The following mouse click actions are available:

Right-click

Modifier + click

Ctrl-click is equivalent to right-click.

Alt-clicking inside an item, with a zoom factor greater than one, reset the current zoom to full view (Factor = 1).

Double-click

Double-clicking on an editable control such as a slider or text box enters keyboard entry mode, double-clicking again validates the new value. Double-clicking anywhere inside a panel switches the panel to full-window mode, where the whole application screen is occupied by the corresponding panel; double-clicking a second time reverts to the normal layout.

Click and drag

Clicking + dragging inside an item, with a zoom factor greater than one, shifts the current scale.

Alt + Clicking + dragging inside an item with a Zoom</link> Factor, allow to setup a new zoom according to the defined selection.

Scroll wheel + click and drag

Turning the middle mouse wheel, if present, affects the current horizontal zoom level of the item under the cursor.

Activating the wheel with the middle button simultaneously engaged shifts the current scale when the current zoom factor is greater than one.
