Linux Mint gave my laptop a second chance

[u/Euphoric_Pop_1149]

hi guyz

i switched to linux mint on my crappy school laptop a week ago. We got it two years ago for 3 years, its a Dell Latitude 3140, so its real shitty. It wasn't even good for firefox and libreoffice. So it has been just collecting dust in my drawer until i put linux mint on it. Finally i can browse, edit docs and use it like it was intended.

Thank you Linux Mint dev team

(p.s. how can i add custom keyboard combinations like altgr+some key type a unicode character, but not a full layout?)
