Run

This menu contains commands for testing code and displaying userforms.

Run Sub/Userform - (F5). Runs the current procedure if the cursor is in a procedure or runs the form if a form is currently active. This command becomes the Continue command when you are in break mode. If a Code window or a UserForm is not active, this command becomes the Run Macro command. While you are stepping through your code this becomes the Continue command.
Break - (Ctrl + Break). Stops execution of a program while it's running and switches to break mode
Reset - Clears the Call Stack and clears the module level variables.
Design Mode - Toggles design mode. Design mode is the time during which no code from the project is running and events from the host or project will not execute. You can leave design mode by executing a macro or using the Immediate window.
