Configuring the alt-tab dialog in Openbox 3.5

By default, Openbox 3.5 has a vertical alt-tab dialog. If you prefer the old alt-tab icon dialog, you can revert to it by adding the <dialog>icons</dialog> to the PreviousWindow and NextWindow actions in your Alt-Tab (and, for me, Win-Tab) keybindings in your rc.xml, as follows:

<!-- Keybindings for window switching -->
<keybind key="A-Tab">
      <action name="NextWindow">
      <dialog>icons</dialog>
      </action>
    </keybind>
    <keybind key="A-S-Tab">
      <action name="PreviousWindow">
      <dialog>icons</dialog>
      </action>
    </keybind>
<keybind key="W-Tab">
      <action name="NextWindow">
        <allDesktops>yes</allDesktops>
      <dialog>icons</dialog>
      </action>
    </keybind>
    <keybind key="W-S-Tab">
      <action name="PreviousWindow">
        <allDesktops>yes</allDesktops>
      <dialog>icons</dialog>
      </action>
    </keybind>

Change <dialog>icons</dialog> to <dialog>list</dialog> to get the vertical dialog. Change it to <dialog>none</dialog> to have no dialog.

In the rc.xml there is now also a new setting to configure the font for inactive text in on-screen-displays, like the alt-tab dialog. If you’ve migrated your old configuration to Openbox 3.5, make sure you delete the OnScreenDisplay font settings in the theme section of your rc.xml and replace it with two settings: one ActiveOnScreenDisplay and one InactiveOnScreenDisplay. This section in my configuration file looks as follows:

<font place="ActiveOnScreenDisplay">
    <name>Corbel</name>
    <size>9</size>
    <!-- font size in points -->
    <weight>bold</weight>
    <!-- 'bold' or 'normal' -->
    <slant>normal</slant>
    <!-- 'italic' or 'normal' -->
  </font>
  <font place="InactiveOnScreenDisplay">
    <name>Corbel</name>
    <size>9</size>
    <!-- font size in points -->
    <weight>bold</weight>
    <!-- 'bold' or 'normal' -->
    <slant>normal</slant>
    <!-- 'italic' or 'normal' -->
  </font>
