Large parts of the user interface’s contents and functionality depend on the current selection. To select a word or an Object in a list or tree, single-click it and it will be highlighted. To select multiple Objects, control-click them or command-click them on a Mac, or use shift-click to select a range of Objects. You can also combine the control and shift keys with the cursor and space keys to select without using the mouse. In a text Editor, you can select by simply dragging the mouse or using shift and the cursor keys.
The context menu of the TextGridLab contains various commands which differ depending on the opened Perspective or View. In most of the following chapters it will be explained what tool functions are possible by calling up the context menu.
