NMS can be scaled to make things bigger or smaller by pressing Ctrl and the plus or minus sign, respectively. NMS is generally expected to be usable at up to 200 percent magnification; however, depending on the configuration, there may be windows that will be too tall to be fully visible (especially on displays with limited resolution). Having a high definition monitor can help.

If it is desired that all environments be scaled, a system environment variable NMS_SCALE can be defined. For example, if NMS_SCALE is defined as "2", the application will be displayed by default at twice the size of the standard view.
