many time you want to create open office presentation , We go to open office via menu and then create and save it. many time we create html page, for that we go to gedit and write <html></html>, write a basic html again and again is boring, How about right click and create document as shown in image !
This is simple hack,
now just create empty file (like open office, shell script, html file etc) and paste into this directory.
They will appear into right click menu.but this will for current user as we are creating Templates in home directory. I do not know how i can create system-wide templates for all users
