Explaining better each part you quoted:
With the options below enabled
(freely translating them to English, the first “disable AI review”; the other is “always disable analysis”)
If I press any arrow key, in the right column of my window, the game chat will be hidden, and will be replaced with the analysis thing. I hate this because what I would want to do with the arrow, when I load a game page, is either scrolling it, scrolling the past move, or scrolling the chat. Nothing else. Left and right right keys navigate the moves, but the fact they do it with the analysis interface show is something I simply do not want. And I repeat: if my opponent or anyone wants to do it, I do not care. I do not want to make it harder for them. My choice must not be their. At most, the site could say that I disabled it, if there is a reason for saying it.
Still with the arrow keys expected use, I will press tab several times to focus the chat. Is there a simple way to scroll it? With the chat history focused (it will focus the username of each message sent before, and eventual URLs, and nothing else, I think; board coordinates are highlighted, but no tab stop for them, which could be nice), if I press the arrow keys, the analysis mode is shown again. This is incredibly annoying! So, to scroll and read the history, I must use only tab and shift+tab. Nothing else. Page up and page down keys also open the analysis thing! A simple but very bad bug: if I want to read the last comment in the chat, and it is long enough to occupy 2, 3 or move lines in my chat window, I cannot see all of it this way. We scroll up to have it below everything shown; then we scroll down with enough tab presses to reach it… after the name of who wrote it is focused, the next focused part will the the message type menu. I did not find a “good” way to see it this way. Another clear bug: The text area where we write our messages has the “suggested text” (it should have a name which I do not know) is written “Message…”. It is written in English, and not in the language I chose to use OGS; I am a translator of OGS and I have checked each and all the strings that could be it; everything with this word is translated; why this is not?
I said that I could not navigate game moves because the view change confused me. I wanted to navigate moves seeing the chat, since I frequently talk above the game. This did not happen, but I said it in a wrong way.
The scroll up and down sentence is also about the chat history. The board always adjust its size to the viewable page area, resizing itself even when the browser makes this a bit smaller in height when I want to search a string in the page. And as said above, page up and page down keys do not work, and shift, ctrl and alt with them neither.
I never checked what kind of code makes sites use keyboard shortcuts. I simply hate not having a way to never let sites use keys or key combinations that I use for anything, since operating system keys, going through window manager keys, and browser keys and even my arbitrarily chosen shortcuts for the browser. There are sites and sites’ situations where I simply cannot go out without losing more than just the site tab (like all the tabs opened in the same browser window, and when this window is a private one, I may lose data and/or time)
So, I am sorry if I write too much. It is mostly a “gift” I have, hard to avoid. Read everything with the time you need. And I thank you very much for all your time and attention with this.
