There are two entry field styles available:
Web Browser
The Web Browser entry field style uses standard IE entry fields, which are compatible with other entry fields in the Windows environment. Full clipboard, insert location, selection and so on will work as it does with other applications. As with other input fields in Windows, the Web Browser input field has an indented thin border around it. For those accustomed to Windows applications, this is helpful because it identifies the entry field locations and their widths. This can also be distracting to users that are accustomed to traditional terminal emulation packages; this field type also requires more vertical space for each line.
If you prefer the Web Browser entry field style you will also want to utilize the Line Height Adjustment setting to ensure that the entry fields vertically overlap to your preference.
Terminal Emulator
The Terminal Emulator entry field style is implemented using direct keystroke processing and direct cursor control. It behaves more like the traditional terminal emulator in that fields are not identified with borders, and the cursor is, by default, in overstrike mode.
For large, busy screens, this may be the preferred style, since the vertical space requirement is less. The style sheet used can also provide a back lit effect on entry fields so that for those unfamiliar with a particular screen, the location and width of fields is not "invisible" as it is with many traditional terminals and terminal emulators.
