If you are using the Maya Editor Plugin or just the Infoviewer to view the Maya documentation in jEdit you may have noticed that the MEL commands documentation is pretty much unreadable due to the font size being too small. Increasing font size doesn't seem to work with infoviewer, so I manually edited the html files and inserted a wherever needed.
I still can't get the substring search function to work, but this fix at least allows you to use the infoviewer and have it docked to the UI. Usually I would just use an external browser, but the infoviewer loads up super fast and is dockable to the sidebars which is great when you don't have a whole lot of real estate to begin with. You can still use any other browser to view the documentation even with the edited html files.
HOW TO INSTALL:
Simply copy and paste all the html files to your docs/commands folder overwriting any existing files (C:Program FilesAutodeskMaya2009docsMaya2009en_USCommands).
