install & setup

install Xilize plugin
Once you have jEdit running, get Xilize2 from the download page on this site. Follow the directions on that page to install it in the proper place.
setup Xilize mode
On first use, the plugin will detect if you do not have an Xilize mode file installed and offer the option of installing one. Having it installed enables highlighting of Xilize markup and other edit mode options.
Note: If you are upgrading from v0.9 use Plugins → Xilize → options to force the update to the new mode file.
configure shortcuts
To configure keyboard shortcuts to run Xilize commands, see the jEdit Tips in the appendix to this guide. It provides an overview for setting up and using jEdit to run Xilize efficiently.
