# How the String Input Enable button works at run time

When the operator presses the String Input Enable button, the string pop-up keyboard or scratchpad opens. The operator types an alphanumeric string in the pop-up and presses Enter. The string is sent to the Value connection at the data source.

If the screen for the computer running the application is too small, the pop-up does not open:

- If the terminal's resolution is smaller than 236 pixels wide by 208 pixels high, the string pop-up keyboard cannot open.
- If the terminal's resolution is smaller than 236 pixels wide by 44 pixels high, the string pop-up scratchpad cannot open.
