# Operating Text Box Controls

When you set a text box control to any mode other than indicator mode, you can change its text from the keyboard or with the mouse.

You can use the following keystrokes when you enter text into a text box control:

- Press <Ctrl-Tab> to insert spaces up to the next four character tab stop.
- Press <Ctrl-Enter> to start a new line.
- Press <Home> or <End> to move to the beginning or end of the current line.
- Press <Page Up> or <Page Down> to scroll the text box up or down one page.
- Text can be selected by holding down <Shift> and pressing the arrow keys, <Home>, <End>, <Page Up>, or <Page Down>.

If the control mode of the text box is hot or validate, a commit event is generated when you change the contents of the text box and then press the <Enter> or <Tab> key or click on another object with the mouse.
