Search the net for URLFOR and "url hacking", "url prepopulation" keywords.

There are special $variable actions in Visualforce: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_variables_global_action.htm, you'd need $Action.Opportunity.New

This is a decent tutorial too (although "url hacking" differs a bit between Classic and Lightning UI): https://www.salesforceben.com/salesforce-url-hacking-for-lightning-tutorial/ or if you prefer SF help: https://help.salesforce.com/s/articleView?id=release-notes.rn_general_lex_navigate_to_record_dfv.htm&release=224&type=5
