In the 'Misc' tab you will find the following parameters:

Keyboard

Enable Type-Ahead

Check this option if you want keystrokes to be sent to a buffer when the screen is still loading so the characters typed during that interval are sent when the screen is once again ready for input.

Automatic Keyboard Unlock

Check this option if you want the keyboard to be automatically unlocked after typing in a protected area of the screen.

PC Insert Mode

Check this option if you want to work in the Insert mode instead of the Overwrite mode when typing.

Sound Alarm

Specify if systems beeps are played through the PC speaker or the PC's sound card. Select 'Disabled' if you don't want any sounds to be played at all.

Dynamic Toolbars

Keep at least one toolbar visible

Check this option to specify that you want at least one toolbar to be visible at the top of the Emulation Display.

Connections

Number of Screens to remember in History

In this field you can specify the number of screens that will be kept in the Screen History.

This checkbox enables Dynamic Data Exchange. This option works only on TE3270 and TE5250 connections.
