Enter sync edit mode if you want to rename a variable, method or another word in several places
within the text.
To enter sync edit mode is simple:
1. Select a block of text. E.g. a function, procedure or just some text.
2. Press the "Sync Edit Mode" button in the sidebar.
3. The background of the selected text changes to lite cyan.
4. Move the text cursor to the variable you want to rename. Notice that the variable
is framed
in the entire block.
5. Edit the name. Notice that the variable changes the name in the entire block.
6. Press "Sync Edit Mode" button when finished.
There are several things that are disabled in sync edit mode, like normal editing, cut/copy/paste
and other functions. Sync edit mode is only supposed to be used to rename a word in several
places in a block of text.
