I have installed Visual Basic Express 2010 with hotfix ENU KB2635973 and ENU service pack 1 KB983509 (Visual Studio 2010 version 10.0.402191.1 SP1Rel).
a) The Bookmarks icons are located in the Text Editor toolbar. There are 4 Bookmarks icons:
a1) Toggle a bookmark on the current line (Ctrl+K,T)
a2) Move the caret to the previous bookmark (Ctrl+K,P)
a3) Move the caret to the next bookmark (Ctrl+K,N)
a4) Clear all bookmarks in all files (Ctrl+K, Ctrl+L)
b) To access to Text Editor toolbar with the Bookmarks icons:
b1) Tools menu --> Settings --> check Expert Settings
b2) View menu --> Toolbars --> check Text Editor
Note: If in Tools menu --> Settings --> the Basic Settings is checked, then the Text Editor does not have Bookmarks icons.
c) The Bookmarks are linked to lines of code like a breakpoint, not to line number. So if I place a bookmark, then add or delete code above it, the bookmark stays at the same code I marked.
d) The Quick Find dialog has a Bookmark All button.
d1) This button is enabled for Current Document, All Open Documents, and Current Block.
d2) This button is disabled for Current Project and Entire Solution.
e) After saving, closing, and reopening the project, the bookmarks are not lost. They stay in the same place I have marked them.
f) After moving the project to a diferent folder in a different drive, the bookmarks are not lost, and they stay in the same place I have marked them.
(E.g.: I moved the project from C:\Users\AFDBAF\Documents\Visual Studio 2010\Projects\Test_Project to G:\Test_Project).
g) The View menu does not have a Bookmarks window. (Also, the View menu --> Other Windows does not have a Bookmarks window). After looking at all the menus, I did not find a Bookmarks window.
