A method to dynamically translate/change IR filters, highlights, etc.
Select another value for P1048_LANGUAGE to see the effect.

Make sure the strings used in the Dynamic Action do not occur in any other <a> element.

Note: the (page) javascript and dynamic action marked /* FOR APEX < 5.0 ONLY */ - used for changing the Column Groups - will not work on Apex 5 or greater. So alas it doesn't work on this site, but will work fine in Apex 4.2.
In Apex 5, the Worksheet Column Groups were added to the Translation Repository, so it's better to use that.
Note that on the Translation Repository page, they are not linked to the page the report is on (no idea why). So if you can't find them, that's probably why...
