- Click on the text.
- A surrounding patch of text (a sentence? a paragraph?) is "locked"
(no one else can edit it) and highlighted, and somehow rendered "editable". 3. Edit, drag text around etc. If necessary, mark other bits of text as being "locked" as well so you can edit them. 4. Press a commit button.
No losks are needed. If several people is editing, they will have an edit conflict, like now. 'Please compare it'. And they aren't too frequent.
