Method GTK2.TextBuffer()->create_mark()

Method create_mark: GTK2.TextMark create_mark(GTK2.TextIter where, int left_gravity, string|void mark_name)
Description: Creates a mark at position where. If mark_name is omitted, the mark is anonymous; otherwise, the mark can be retrieve by name using get_mark(). If a mark has left gravity, and text is inserted at the mark's current location, the mark will be moved to the left of the newly-inserted text. If the mark has right gravity, the mark will end up on the right of the newly-inserted text. The standard left-to-right cursor is a mark with right gravity (when you type, the cursor stays on the right side of the text you're typing). Emits the "mark-set" signal as notification of the mark's initial placement.
