When using the SAS^® session editor within SAS^® Life Science Analytics Framework 5.4.1, the Ctrl+Shift+U keyboard key sequence is expected to cycle through the lower, upper, and proper case settings for the selected code or text.

If the selected code or text begins with a special character (for example, an underscore or asterisk), the keyboard key sequence does not cycle through the various case settings properly. 

A fix for this issue is being considered for a future software release.
