Moving in text files
You can move in files by using the arrow keys on the keyboard, the scrollbars, the toolbar navigation icons the Go To Line dialog box. The left and right file overview graphs allows you to go quickly to interesting places of the files.
Macros can be used to navigate within the documents. Currently, the macro buttons "Previous/Next Difference Inside Line" and "Previous/Next Difference Inside Line, skipping blanks" are provided. They can be parametered through scripting (you can add new buttons skipping other things than blanks), and you can add them shortcuts in the shortcuts panel of the Preferences.
