Kibitzer

Kibitzer is a free keyboard viewer. It displays all characters accessible via the keyboard, making it easier to deal with special characters used by the Dyalog application development environment.

Note that Dyalog Version 11 comes with APL Team's Kibitzer, which is installed by default. Updates to the latest version can be downloaded from this page.

The current version of Kibitzer is 2.4.1
