Forexample, the context menu in the Edit Window or aselection menu in Tools → CAM Editor for inserting ordeleting Fix Points. The popup menus are closedautomatically when the selected function is executedor if any other location on the screen is clicked withthe left mouse button.Function KeysFrequently used functions are assigned to function keys:[F1] Access on-line help[F2] Skip to the next bookmark[F3] Find next (if “Find” has been used)[F4] Check the syntax of the program[F5] Execute the program (see also Execute)[F9] Single-step through the program (debug mode only)[F11] Access on-line help for system process information[F12] Open the “Command List” for simplified programmingThe function keys will be described later in this chapter where appropriate.[Esc] keyIn standard Windows applications, the [Esc] key normally closes the currently active window. However, inthe APOSS Window, the [Esc] key will automatically open a connection to the default controller if nocontroller has yet been connected. If a controller has already been connected, then the [Esc] key will abortany program currently executing on the controller.NB!:If an executing program is aborted while the drive is rotating, then the drive will slow down withthe maximum allowed deceleration.Reconnect a Lost ConnectionWhen an active connection to a controller is lost (for example, if the controller is powered off or the commu-nication line is disconnected), then the APOSS Window connected to that controller will display a “Lostconnection” message in its title bar. However, the window will remain “associated” with that controller.Pressing [Esc] (or executing any command that needs to talk to the controller) will cause the APOSSWindow to attempt to reconnect to the same controller. This behavior becomes relevant only when there aremultiple controllers available on the communication line.
