X refers to the sentence/context of the message you're replying to. (^) the direction of this symbol, will determend the direction of the message you're replying to. X^ means
one message up to the right (usually your own message). ^^^^^X means 5 messages up to the left. This symbol can be displayed on it'
s own, usually this means that the person just wants you to look at this message, but it depends on the context of course.
X can be used in capital or not, you often
don't
even use X on It'
s own, but it can be used for directions if you
don't have a/any sentence/context.
X^ and ^X or ^^^ are mostly used in chats for practical reasons:
I'm fine
Are you fine?
x^
(This conversation points to that you have all ready
said that you'
re fine and you
don't want to waste time on writing it again).
