#### 4.10.27 GotoBookmark

Syntax: `GotoBookmark [`n`|`-`]`
Abbreviation: `GBM`

moves the cursor to the nth or - automatic bookmark, assuming that bookmark has been set; see SetBookmark. If the optional n argument is not specified, it is assumed to be zero. When successful, the ‘`-`’ automatic bookmark is set to the position in the document from which the command was issued, so that `GotoBookmark -` returns you to the location from which you last issued a `GotoBookmark` command. Subsequent repeated `GotoBookmark -` commands toggle you between the two locations. Each document's valid bookmark designations are 0 to 9, and the ‘`-`’ automatic bookmark.
