9. Tips and Tricks

This section is a collection of tips and tricks for making your life easier.

9.1 Using the CLI (command line interface)

You should run IceWM with "TaskBarDoubleHeigth=1" because that will enable the CLI (see What is the blank bar in the task bar good for? for some more information).

The CLI is especially useful if you rather frequently need to access man pages and don't want to have xman hang around all the time.

If you enter "man perl" and press "Ctrl-ENTER" an XTerm will pop up displaying the main Perl man page. If you press "q" not only the man page no longer is displayed but the XTerm will terminate, too.

This only is one example of how to use the CLI. You can use it to issue any other command as well. A problem that might occur is that the XTerm will terminate before you had time to read the output of a command (it terminates as soon as the command is done).

In most such cases it is sufficient to pipe the output through "less" (this is one of the rare cases you cannot use "more" because it terminates after displaying the last line). However, there are cases (mainly programs that write colorful output such as "ls") that may result in trouble with "less".

Fortunately Linux (any Unix version?) offers a solution to these cases, too: The "sleep" command. It sleeps some time, then terminates. So you could use 

    ls $HOME/bin --color ; sleep 1m

to list all programs in your "$HOME/bin" directory. The "sleep" command will wait the given period of time (in this case a minute) before the XTerm automatically will close (you can use "Ctrl-C" to abort the "sleep" command before that time went by).

9.2 Switching Desktop using keyboard

You are accustomed to a window manager that allows you to switch between virtual desktops using your keyboard? IceWM allows for this, too.

Before I describe how to switch between virtual desktops I want to describe how to control their number. Imagine that your "$HOME/.icewmrc/preferences" has a row reading 

    WorkspaceNames="1","2","3","4","5","6","7","8","9","0"

This setting results in ten virtual desktops and ten buttons in your taskbar looking like this: 

    +---+---+---+---+---+---+---+---+---+---+
    | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 0 |
    +---+---+---+---+---+---+---+---+---+---+

If you name less desktops you obtain less if you name more you get more.

For understanding how switching virtual desktops works in IceWM you should imagine that the buttons represent your virtual desktops and that these desktops are arranged in one long row.

You can imagine two ways of switching between desktops:

IceWM has both ways:

"Cursor_Left" ("Cursor_Right") represents the key that moves your cursor one character to the left (right).

If you are using "Ctrl-Alt-Cursor_Right" on the rightmost desktop you switch to the leftmost desktop. From here, "Ctrl-Alt-Cursor_Left" brings you back to the rightmost desktop.

What if you have more than ten virtual desktops? In this case "Ctrl-Alt-n" will only work for the first ten desktops while switching to the left or right still works for all desktops.

IceWM has another feature to offer: You may not only use your keyboard to switch desktops, you can also use it to move windows from one desktop to another. The next section is on this (you should read it, too).

9.3 Moving windows between desktops using keyboard

In the previous section I explained how to switch between desktops. If you didn't already read it you should do it now because moving the active window to another desktop works almost the same like switching to a certain desktop. All you have to do is pressing the "Shift" while switching to the desktop:
