I too find that keyboard jogging behaves strangely with version 3233.
By default, the keyboard plugin disables jogging following start up. After keyboard jogging is enabled, say by clicking the Notification bar icon, I find that the arrow keys, which should cause normal jogging, have no effect. Ctrl-arrow, for incremental jogging, does work however. Both are correctly set in the keyboard plugin, so would be expected to take their respective actions.
I have found that the simple work around to this is to modify the first run of the PLC script so that the keyboard plugin is enabled rather than disabled following start up. This ensures correct operation of all keyboard jogging functions.
I am using Windows 7 (32 bit with CSMIO-IP/A and 64 bit with Simulator) and the keyboard plugin is dated 4 November 2016.
