Unless I am totally misunderstanding the question/suggestion,
you can use ALT-B to create a Bookmark.
ALT-PageUp and ALT-PageDown will cycle through them.
But maybe you are asking simply to put them on the toolbar?
When I am writing code, I find that the keyboard is handier than the mouse.
i agree, i used it very often. left-alt & b with one hand is not good to use.
i can not memory so much key combinations, i like to have a menü or icon.
and if one of the key combination did not react you modify the code accidentally.
the tool bar using only 40% of my screen, there is a place for it
