Confluence on demand, Wiki Page Lists - Pressing SHIFT-tab does not outdent in a bulleted list, tab indents but shift tab also indents, only the gui toolbar outdent is able to outdent.
Happens with both Chrome Version 23.0.1271.64 and Firefox 16.0.2
I saw this similar related issue that is noted as fixed a long time ago, but this is currently broken and repeatable for me.
