**Blender Version**
Broken: 276b
question 1: in the space search menu, there is no 'ctrl+b(render border). But we can find it in view menu
question 2: what is the 'zoom to border' I labeled as 3 since there already 1?
question 3: there are 2 operations who have same shift+b shotcut, but when I choose one of them, no sub-menu appear, does that means?
