### Set Video Mode

```
Action    name: SetVideoMode
 
```

This command changes the current video mode. The list of allowed video modes is kept in the IDATUI.CFG file, the SCREEN\_MODES parameter.

Please note that there are two instances in this variable: one for MS-DOS and another for Windows.

If you use the MS DOS version, you need to specify the screen mode numbers valid for you video card in SCREEN\_MODES. Otherwise, this command will not work.

### Invoke external help

```
Action    name: ExternalHelp
 
```

This command invokes an external help.

In the MS Windows version of IDA, it starts WinHelp with the parameter taken from the cursor location.

The HELPFILE parameter in IDATUI.CFG/IDAGUI.CFG points to the help file name.

### Keyboard layout

```
Action    name: KeyboardHelp
 
```

This command displays the current keyboard layout.

You can change the layout in the configuration file

```
        IDATUI.CFG (for the text version)
        IDAGUI.CFG (for the GUI version)
```

This command is available in the text version only.
