Mouse Buttons

„Click“ means to press and release a mouse button once. „Double-click“ means to rapidly press and release the left mouse button twice.

Click with Left Mouse Button

To select an option, execute a command, select an object, or activate an object icon, place the mouse pointer on that option, icon, command, or - in the graphics - on the border or the centre line of an object or line object and click the mouse button.

Unless stated otherwise, mouse actions always refer to the left button. If you are left-handed, or the mouse was configured differently, use the appropriate button instead.

Multiple Selections

CadnaA features dialogs with lists where you can highlight and select several rows at the same time.

Selecting one row

Click the desired row using the left mouse button. Clicking a different row deselects the one selected before.

Selecting several consecutive rows

Click the first row using the left mouse button, press and hold down SHIFT while clicking the last row to be selected. All rows lying in between are highlighted and selected as well.

Selecting several rows in an arbitrary sequence

Press and hold down the CTRL key while clicking the desired rows.

Double-click with Left Mouse Button

Double-clicking an existing object or a data record in a table opens the pertinent Edit Object dialog enabling to enter the relevant parameters.

Click with Right Mouse Button

Clicking with the right mouse button means to rapidly press and release the right mouse button. Depending on which mode you are working in, using the right mouse button has two different effects.

Entering an Object & opening its Dialog

When entering an object with the mouse in the main window of CadnaA, the insertion process for the object is completed by clicking the right mouse button once. By a further click with the right mouse button the object dialog is displayed.

Clicking on an object with the right mouse button in edit mode or a data line in a table, a context menu (see Chapter 12 - Context Menu) is displayed.
