Is there any shortcut key to align code in Geany editor?

For C, C++, C++/CLI, C#, and Java

You can achieve a similar behavior with Artistic Style 2.04.

1. Download the newest version, current 2.04 (do not use apt-get to install because then you will get the older version 2.03 and this version will not work for this scenario because it do not accept piped output)

2. Install Artistic Style -> follow the install doc (/astyle/doc/install.html) in the download (make then make install)

3. Add a custom command to Geany:
   
   
   
   

   bash -c "astyle --indent-classes -Y"
   
   To customize this look at the Artistic Style documentation

4. Select an text area and press Ctrl+1 to run the first Geany custom command
   
   

For HTML

You can use tidy, tidy can also compile your html code if you use geany.

1. Install tidy: sudo apt-get install tidy

2. Create a custom command (example):
   
   bash -c "tidy -xml --indent auto --indent-spaces 2 --quiet yes 2> /dev/null; true"
