These keyboard shortcuts select multiple messages or folders instead of selecting multiple attachments (looks like attachment area does not get/keep focus). It is still possible to select multiple attachments using Ctrl + mouse click, but this is very inconvenient when there are many attachments. When composing new message, selecting multiple attachments using keyboard works well. Reproducible: Always Steps to Reproduce: 1. Click message with multiple attachments 2. Click on one of the attachments 3. Press Ctrl + A to select all attachments Actual Results: All messages in folder are selected (conversation view is displayed) Expected Results: All attachments of appropriate message should be selected (to further manipulate attachments) It is the same when trying to select attachments using Ctrl + Arrow
