How do you chat on Blindfold RS games?

How do you chat using a braille display on RS games? A few people tried chatting with me, but I couldn't respond.

#1 What I know

The only thing I know is swiping right with three fingers to chat.
Or, if you have a Bluetooth Keyboard, hold down CONTROL and press 2, not F2, just the regular number.

#2 Kind of an adjacent question

Kind of an adjacent question regarding chatting - on both the PC client and the IOS client:

- Is there any way to get it to repeat the last chat message?

I find it frustrating that sometimes I accidentally miss a chat message due to inputting a game command or something right when the chat message comes in. It leads me to basically having to stop doing anything the minute I hear that someone is writing a message for fear of missing it.

#3 I think that's control page

I think that's control page up and gown on PC, but I use a Mac. Had to go reread the client documentation to figure that out. I wish they'd allow you to read that within the client itself, as I've had to force quit it since it became unresponsive when I switched to Safari and back again.
