To raise a partially concealed window to the top of the window stack, or in other words to the front of the display, position the pointer on the window's frame and click Button 1. Be sure that the pointer is not resting on one of the window frame command buttons: minimize, maximize, or Window Menu (see Figure 2-2).
The window manager also provides default methods for raising a window from
the keyboard, as shown in Table 2-2.
Table 3. Raising a Window from the Keyboard
| Pressing these keys... | Does this... |
|---|---|
| <Alt> <Tab> | Raises the next window in the stack and moves input focus to that window (explicit focus only) |
| <Alt> <Shift> <Tab> | Raises the previous window in the stack and moves input focus to that window (explicit focus only) |
| <Alt> <Escape> | Raises the next window in the stack without changing the input focus |
| <Alt> <Shift> <Escape> | Raises the previous window in the stack without changing the input focus |
When you are using an explicit input focus policy, raising a window to the top of the stack also sets the input focus to that window. If you are using a pointer focus policy, however, the window manager does not automatically set input focus to the raised window. In other words, a window can continue to receive input even though it is not at the top of the stack. You can, however, set a resource in the the X configuration file to move a window automatically to the top of the stack when you set input focus to that window (see Chapter 5).
