how recognise same text but different case sensitive ?

Trying to click same text name but different case sensitive, example
Ex: one webpage got text “link1”
Other webpage got text “LINK1”
How do I click using one command ?

Please help out

What do you mean by “one command”? Are you trying to make the search case-sensitive or case-insensitive? It’s case-insenstive by default, so this code:

Click text:"link1"

should click whichever variation it finds. If you wanted to click on something with specific capitalization, then you would need two commands and you would need the caseSensitive property:

Click text:"link1", caseSensitive:YES
Click text:"LINK1", caseSensitive:YES
