Macro text

So I'm not sure if riot is ok with macros because I read they don't want people to use them for abilities and such. I am just wondering if riot implements measures to make macros harder to use. I have made a profile for league client in my Logitech Gaming Software for my keyboard macro keys. My keyboard is the Orion G910

Basically I want to say a few phrases like "Thanks :D" or "We got this guys!" and I'm not able to. One thread mentioned using the MR button and I can do that, but it sometimes makes me flash or open a menu if the first or last letter of the macro is a hotkey even if I program it to press Enter after. Another issue I have with this is, for some reason, I have to program it to press ESC in the end of the MR so it doesn't pop up the settings menu. Lastly, after getting these macros ok, and working around the issues above, it disables my keyboard from doing anything else. I cant press my abilities at all. Maybe I'm just new to macros, but if I assign keys without MR league doesn't recognize it for some reason. Any help or insight would be awesome

p.s. without using MR button the default profile for my G6 button is "664mr keyboard button" no idea what that is or if it is part of this, but there you have it.
