Actions
In BSCW, an action may be triggered by selecting a menu entry or clicking a button, link or icon, each representing the action. In the Web-based user interface these action triggers may take the following forms:
Menus:
Top menu bar, e.g.
Context menu and action menus, e.g. 
Buttons:
Action shortcut bar
gives
access to frequently used actions.
Instant access bar
Example: 
opens your
clipboard.
Navigation bar
Example: ‘:your-user-name’ opens your home folder.
Multi-selection toolbar, e.g. 
(cut)
or 
(delete)
Links or icons in the entries of a folder listing
Example: 
shows the member group
of a workspace.
With the obvious exception of the action shortcut bar, the actions triggered by buttons are simple navigation actions: they open and display a new page showing another folder, a document, the members of a folder, a user info page, etc.
For the rest of this section, we focus on the actions triggered via menus, which need a bit more of an explanation.
Keep in mind that the actions made available to you in the diverse menus also depend on
o the level of proficiency you have set in your preferences and
o the role (i.e. access rights) you have with respect to a folder and to the objects it contains.
