System-wide change of definitions e.g. "Accounts", "Contacts"... HOW?

[superbcrm]

Hello.

We are evaluating SugarCRM (using the online 30-day demo).
Our business is travel, we need a lot of customization.

I have changed the names of tabs etc, to reflect our business needs
e.g. "Leads" to "Enquirers", "Contacts" to "Customers", etc.

The PROBLEM is:
This is just a "cosmetic" change of the tabs - in every other instance, the default definitions (Leads/Contacts...) persist.
So in most layouts, our user is suddenly confronted with "create new Contact" (instead of Customer), a drop-down list that shows leads/contacts and so on...

The QUESTION:
Is there a way to do a system-wide, universal change of these terms?

I gathered from the forums that you can do it by changing the actual code...but it sounds like a lot of work and also you need to be careful about the cross-referencing in the files, sound too complex and error prone...or is it?
As I am working with the demo, I do not have access to code files & changes, so PLEASE tell me how this can be done (if at all) easily.

Thank you very much.

You can change this using the Studio: see 'Labels' section under the each module. ( 'Edit Labels' link in 4.5.X version)
Anyway such sort of changes will take time if you don't have direct access to the files.
