I have a longtext field in my form. For some reason, Ctrl-A (select all text) doesn't work for plain text. I.e., when I set Text Format to "Plain Text" - Ctrl-A doesn't do anything. But when I set Text Format to "Rich Text" - Ctrl-A works as expected, i.e. it selects all text in the field.
So, why Ctrl-A doesn't work with plain text and how to fix it? Thanks.
