Installed per instructions but can't get it to work.
Tried on Sublime Text 3.1 and 3.1.1 on OSX
Specifically followed these from README.md
"chord" command Ctrl+K, Ctrl+F (this mean hold Ctrl, press K then press F, release Ctrl) and also available in "Selection" menu.
Crtl+K deletes my selection, so chord command doesn't work
Selection / Format menu shows several items, but cannot click on "Indent XML" because it is disabled (greyed out)
