TinyTERM for Windows includes an onscreen keyboard below the main window.
This requires that a layout file with the extension
be in the user's Documents\TinyTERM folder in Windows. The file must then be
referenced by the
frameKeyboardFile argument in the
The onscreen keyboard can be selected, or turned on and off, via the
frameKeyboard setting in the
tpx file. Three layouts are included in the
- UNIX: provides F1-F12, and the standard island and arrow keys
- TN3270: provides F1-F12, as well as several 3270 special functions
- TN5250: provides F1-F12, as well as several 5250 special functions
This file is also available in the
C:\Program Files (x86)\Century\TinyTERM folder.
Creating an Onscreen Keyboard Layout
It's also possible to create additional button bar layouts by editing the
frame.ttkeyboard file. Before making any
changes to this file, make a backup copy so the original settings can be restored if
needed. You can also download a copy here.
frame.ttkeyboard is an ASCII text file that contains the existing onscreen
keyboard layouts. For example, the UNIX layout is defined like this:
Each line of key definitions generates a single row of keys. The above has one line,
which corresponds to this button bar:
The first three arguments control the general appearance the button bar,
regardless of the layout selected.
-spacing is the number of pixels between keys
-margin is the minimum number of pixels for spacing from each edge of the keyboard
-fontSize is the maximum size of the primary key labels
The next important argument is the keyboard name, in this case
The + sign identifies the start of a new keyboard. It does not display as part of
the layout name, nor is it needed by the
Following that is the
-keyboardHeight argument. This sets the number of pixels for the
keyboard's height. It can be set in the general settings above,
if desired. If it were, this option would override it.
Everything after the name is considered part of the keyboard layout,
until another + sign is reached. There also needs to be one full blank line after each
layout, even if it's at the end of the
Lines can also be started with the # symbol, to create comments. They will not be displayed as
part of the layout.
The remaining lines are the actual key definitions. A keyboard layout may include
any number of rows of keys. These will be placed in the available space at the best
There are three ways to define a key:
- A single typed character
Any single ASCII character placed by itself in a keyboard row will generate a
key for that character
- Enclosed within square brackets [ ]
The function keys in the example above are all defined this way. Each section of
the key definition is set off with two semicolons ;; with the key label
as the first argument.
- Preceded by the escape character \
Because certain characters are used in key definitions, they
must be escaped to be used as individual keys. The \ also indicates octal or
hexadecimal values, or special characters in a key sequence.

Using a Custom Keyboard Layout
Once a new layout has been added to
frame.ttkeyboard, the file must
be saved in ASCII format. The new layouts will be available the next time a given
.tpx file is opened.
