 Select All: The effect depends on the context in

which the command is used (see online help).

Selected networks can be cut, deleted, and copied, as well as inserted into blocks
of the same language.

Blocks in the catalog of program elements can be opened with the right-hand
mouse button.

If you select a connection in an FBD box or a parameter line in STL and then press

 Block Address: The cursor is positioned at

the address entered.

When a source file is generated, the dependent blocks can be generated at the
same time, if required.

The key combination CTRL+W or SHIFT+CTRL+W enables you to search

times in succession.

You can enter a message text at the call interface of a message-type block (use
the right-hand mouse button to select the menu command Special Object

 Message).

The message attributes of the actual parameter of a called block are automatically
transferred to the formal parameters of the calling block.

When an online block is opened, the operating status of the programmable logic
controller (PLC) is displayed in color in the status bar. During monitoring (menu
command Debug 

 Monitor), a colored progress bar is displayed in the status bar;

when the function is deactivated, the operating status replaces the progress bar.

Local symbols from data blocks are displayed (“Symbol information for data bits”).
