Problem with alt key in some terminals

[yousef8192]

Hello, recently I've heard about tcell library and that it is being used in many TUI applications and tools that I use on a daily basis, so thanks a lot for all the maintainers and contributors for developing this amazing library!

Now for my issue, it is regarding the lf file manager so I first opened it over there in its issues page, but some of the maintainers suggested that apparently it seems that the issue is actually involved with the tcell library. I've described the issue in details over there please do check it out through this link :
gokcehan/lf#1773

If there are further information needed that I didn't provide please let me know.
Thanks a lot in advance for your time and help!

It seems like this problem relates to separating the key press vs. key repeat and key release events. There are edge cases here.
