i want the gedit plugin for zooming the text in file.when i clicked on the Edit-preference-plugin it shows me below message,where i couldn't find plugin.
If gedit has missing plugins, make sure you have the gedit-plugins installed.
sudo apt-get install gedit-plugins
After that, (you probably need to restart gedit) you will have a plugin called "Text Size".
Make sure the plugin is enabled, and you will be able to "zoom" (i.e. change font size) using Ctrl + Mouse Wheel.
This is the list of plugins available in the gedit-plugins package
$ apt-cache show gedit-plugins
[...]
The following plugins are included:
* Git: Git differences
* Bookmarks: Easy document navigation with bookmarks
* Bracket Completion: Automatically adds closing brackets.
* Character Map: Insert special characters just by clicking on them.
