I would add that I don't really know the iPad (as far as these functions are concerned) but the Kindle Fire (Amazon Silk browser) is AWFUL.
- If the quoted material (or even one's own original post) exceeds the depth of the form entry area, there is no way to scroll WITHIN the form entry area. (Not terrible for the forum in the long run, because it forces me to keep my posts short. But damned awkward.)
- The interface for selecting (highlighting) text selectively is VERY awkward. It has two little triangle thingies that you're supposed to be able to drag around to denote the start and end of your selection, but:
- It's inconsistent in how to invoke those to begin with
- accidentally touching the screen anywhere makes them reset or disappear
- positioning them just so is difficult, because when you pick up your fingertip, they often move over a character or two
- once you do have what you want selected, performing an action on it (cutting, deleting, applying a style, etc.) involves manipulating either the soft keyboard or the screen, and is very likely to abandon your selection in the process.
I maintain it's just badly designed, and hope it is improved in an OS or firmware update.
As a complete workaround, what I sometimes do is hit Quote All, Select All, Cut or Copy, then switch over to the word processor. The word processor has the same issues with selecting text, but at least I can see and manipulate all of a longer post. Once I have composed what I want, I then Select All again, Copy or Cut, go back to the browser, Paste, and Preview/Submit.
