 Up Next:
 
-* Make Fn keys execute nth command in the tags buffer
 * check for file changes on save
 * check for file changes when window regains focus
 * Right click in tags region should search edit region
-* Add keyboard shortcut to highlight the thing under the cursor
 * 100% coverage with unit and unit-integration tests
 
 Tomorrow-ish:
 
+* Make Fn keys execute nth command in the tags buffer
 * selecting text should set PRIMARY x11 selection
 * Add a SaveAs tag that takes an argument for the filename to save as
 * Add a GoTo tag for ctags lookup and line number jump (or right click magic?) 
-* Add a ctrl+space shortcut to autocomplete ctag
+* Add keyboard shortcut to highlight the thing under the cursor
 * off by one error on scrolling up with wrapped lines
 * tab inserts dont coalesce like one would expect
