-===== Customize the font in clock panel plugin ===== 
- 
-You can use [[http://library.gnome.org/devel/pango/unstable/PangoMarkupFormat.html|Pango markup format]] to customize the font in clock panel plugin. Switch to custom format (only available with digital layout) and use tags inside the format string. 
- 
-For example: 
-  * ''<nowiki><span font_desc="URW Gothic L Book 18">%R</span></nowiki>'' 
-  * ''<nowiki><span font_desc="bold 12">%R</span></nowiki>''

-===== Use mnemonics to create Thunar Custom Actions ===== 
- 
-When you create a [[http://thunar.xfce.org/pwiki/documentation/custom_actions|Thunar Custom Action]] you can set the name with an underscore "_" before a letter to use it as mnemonic.  When you right click in a Thunar view, you can type the letter to access your custom action.

-===== Other Unique Xfce Features =====+===== Do maths with xfrun4/appfinder ===== 
 +  * What you get: input simple mathematical expression, like 5+5 or (5+5)/3 or .5*10, in xfrun4/appfinder, and get the result as notification. 
 +  * Requirement: notify-send 
 +  * Save this script as bcme.sh, in your home directory:
  
-====== Add newlines to a panel =======+  #!/bin/sh 
 +   
 +  precision=2        # number of digit for floating value 
 +  notify_time=20000  # number of milisecond the notification show 
 +   
 +  res=`echo "scale=$precision;$@" | bc`   
 +  notify-send -t $notify_time "$res" "=$@"
  
-Xfce allows full control over multi-line panel configuratinos, via the Separator component.  Simply add a separator to your panel, move it to where you'd like a new line to begin, edit its properties, and change its "style" drop-down to "New Line."+  *Add custom action to Application finder : 
 +    * Type : Regular Expression 
 +    * Pattern : ^([0-9]|\(|\.).* 
 +    * Command : /bin/sh ~/bcme.sh \0 
 +    *  (check) Save match in command history

 +===== Toggle panel autohide ===== 
 + 
 +Short Bash script to toggle the autohide property of a panel, so you can bind for example a keyboard shortcut to quickly show and hide a panel. 
 + 
 +<code bash> 
 +#!/bin/sh 
 + 
 +test -z "$1" && echo missing panel id  && exit 1 
 +test ! -z "`echo $1 | sed s/[0-9]*//g`" && echo bad panel id  && exit 1 
 + 
 +CHANNEL=xfce4-panel 
 +PANELID=$1 
 +PROP=/panels/panel-$PANELID/autohide 
 + 
 +if `xfconf-query -c $CHANNEL -p $PROP >/dev/null 2>&1`; then 
 +    xfconf-query -c $CHANNEL -T -p $PROP 
 +else 
 +    xfconf-query -c $CHANNEL -n -p $PROP -t bool -s false 
 +fi

 +===== Control per-window transparency =====
  
 +Xfce lets you control the transparency of any window by horizontal scrolling on the titlebar. Starting with 4.12 though, it has been disabled by default. To enable this, open **Settings Editor > xfwm4** and change ''horiz_scroll_opacity'' to true by clicking the checkbox.
