adding language key

OC: 3.0.2
Theme: Journal 2

Hi everyone.
On a product page you may have 2 "add to cart" button. The one for the actual product, and some more for your related products at the product page bottom, before footer. I wish to make related products button text to "See Details" instead of "add to cart".
I then modified the following:
1. in the product language file , i added a key $_['button_seedetails'];
2. on admin panel theme editor, i modified the product/product file, line 328 that is included in the related product <div>, i changed {{ button_cart }} to {{ button_seedetails }}, and saved.
3. Refreshed cache theme, browser.
But i haven't been succesful.
Anything else i need to change? Or what would be the correct way to add a language key?

Thank you all for yout time and help,
lolo.

Post here and you problem is solved (after payment)

Hi, thank you for your suggestion so i could learn about the commercial forum. I guess it is more specialized than freelancer.com and alikes, but i hope i can find support from this community.
Anyway, always good to know about this option.

Hi everyone,
so i kept the new key in the different product language file, but this time i modified theme product/product file from default theme AND from journal 2 theme that i am using currently.
Still no improvement, I can not use the new language key $_['button_seedetails'].
Any suggestion?
Thanks for your help.

well it wont work if you havent edited the controller file accordingly

You have added on you language?
catalog/language/xx-xx/xx-xx.php

That could be the point, in the MVC-L system, I modified the product/product L (language) and V (view=theme) files but i did not find any clue on what to do with the C (Controller) file.
Any suggestion?
Thanks for your help

I added the language key in the different language file as i mentioned in my first post, the catalog/language/xx-xx/product/product.php.
I just now modified the general language file you mention, catalog/language/xx-xx/xx-xx.php, but result is the same, new key not used.
I clear all OC cache, browser cache, no improvement.
Update on 17/ OCT/2020: it actually worked. After a coupe of days i did what i mentionned above. I was out of guess. And then, it appeared. When i installed OC, cart has been malfunctionning for a couple of days too. i guess there is something in webhosting that takes time to adjust, and clear cache is not enough. Cheers.

Just added in language file and show just fine on Default theme

Thanks a lot for your help, but this is a second button. So you are saying this should work for any button? The one i want to modify is the "Related Items" button. At the bottom of each product page when you link "related products", that is why i modified the key in the product page theme in the "related products" <div>.
Thank you for your confirmation

You mean Add to cart from Related products when you are on a Product age?

Correct, that is the one. i wanto it to say «see details» when the product button to add to cart still mentions «add to cart».
