electrum wallet 2.8.3 can't find my old receiving addresses

Hello all !
I am starting to use electrum wallet, on my windows machine.
First I made an transaction and it was done well. When, after some days I was going to do another transaction the receiving address changed ! I know that receiving addresses keep changing and that is a good thing, but I want to know :
Where can I find my old receiving addresses ?
If I make a transaction to that old receiving address will I still receive the btc ?

There are lots of topics around for electrum wallet ! Searched but didn't find something that answered my questions
PS: didn't do an exhaustive search, but went through several posts before creating this thread !

EDIT : I found it out where are the older addresses.
If anyone interested in knowing it is just from the tab : Wallet -> Addresses or simply do CTRL+A and you will find your older addresses.
Knowing this, I guess I can use my old addresses, and I will still receive coins if I transact with them !
