The **RBNONE and **RBSELECT submenu sections of the MNU file (aclt.mnu) control the content and behavior of the right-click shortcut menus. When no objects are selected in AutoCAD LT, the active right-click menu is **RBNONE. If one or more objects are currently selected, the active shortcut menu is **RBSELECT.
If text has been entered on the command line, a right-click will automatically execute the text as a command and will not display the right-click menu.
**RBNONE and **RBSELECT are submenus of the Pop18 section of the MNU file.
The following example shows default contents for the shortcut menus.
**RBNONE
[Clipboard Tools None Selected]
ID_RBLast [$(eval,"&Run "$(getvar,cmdonenter))];
[--]
ID_RBPaste
[&Paste]^C^C'_pasteclip
[--]
ID_RBUndo [&Undo]^C^C_u
**RBSELECT
[Clipboard Tools]
ID_RBLast [$(eval,"&Run "$(getvar,cmdonenter))];
[--]
ID_RBCut
[Cu&t]^C^C'_cutclip
ID_RBCopy [&Copy]^C^C'_copyclip
[--]
ID_RBProp [&Entity Properties]^C^C^Pai_propchk ^P
To customize the contents of the shortcut menu displayed when no objects are selected, modify the **RBNONE section of the MNU file. To customize the contents of the shortcut menu displayed when one or more objects are selected, you can modify the **RBSELECT section. Shortcut menu label syntax is the same as any other pull-down or cursor menu label syntax.
