Visual Build uses tool tips extensively to aid in creating and debugging steps and macros.  Tool tips are displayed when the mouse cursor is held over a field for a couple seconds.

 

Step Panes, Macros Pane, Properties Pane, and Watches Pane: If a column contains macros or is longer than the column width, the cell value with all macros expanded is shown in a tool tip (if the field contains a script expression and the Shift key is held down when hovering, the script code is also evaluated and displayed in the tool tip).  For the Build Rule column, the build rule is displayed (hovering while holding Shift down will display the result of the rule evaluation [true or false]).  When scrolling the view, the name of the top item is shown in a tool tip.

 

Step Properties and Macro Properties dialogs: If a field contain macros, the value with all macros expanded is shown when the mouse is held over each field (if an undefined macro is found in the field, it is left unexpanded).  If a field contains a script expression, if the Shift key is held down, the script code is also evaluated and displayed in the tool tip.  To copy the selection to the clipboard with macros expanded, type Ctrl+M; to copy with macros and script expanded, type Ctrl+Shift+M.

 

Insert Macro Dialog: The macro's description is displayed in a tool tip when the mouse is held over a macro in the list (the description, value, and type can also be displayed in columns in the dialog).

 

Note: Tool tips are not displayed for encrypted properties.
