Just to clarify: there were older Tools Releases where only the left side ALT keys were able to activate the shortcut keys. I remember testing this out at a client last year. They were on 8.95.xx.
However, since DisableRightAltKey was added as a flag, this should no longer be the case. In the [OWWEB] section of your JAS.INI there should be the setting:
DisableRightAltKey=FALSE
If this is set to TRUE, then only the left side ALT key will work. This was done for compatibility with certain language implementations. Check your JAS.INI to be certain what yours is set to.
