no language file to change the first 'proceed to checkout' to 'proceed to cart'.

[Paul Buisson]

ps1.7.8.0, default classic theme, add an item to cart. the following "product successfully added to your cart" modal has a button reading "proceed to checkout". I want this button to read "proceed to cart". when in the cart, there is a button that reads "proceed to checkout", I want that to remain as "proceed to checkout". The UX of clicking 2 "proceed to checkout" buttons back to back is confusing to visitors, which is why I want the modal's button to read "..to cart" instead of "..to checkout". There is only the single entry in the language file, and as stated, I only want affect the button verbiage in the modal.

using this article 

it clued me in to go edit line 92 of /themes/classic/modules/ps_shoppingcart/modal.tpl

which has served my purposes outlined above. special thanks to @Verlonimo

So hopefully a Moderator will mark this as solved, as I do not see how to do that myself. Hope this solution helps others, I did not find anything about this text edit anywhere else.
