The Find bar (Ctrl + F) in Firefox offers a “Match Case” option to help you perform case-sensitive searches on a web page. If you type “RAM” in the find box, the browser will only highlight the phrase “RAM” on that page and not Ram or ram.
By default, searches are case-insensitive. You can make your search case-sensitive by using the case filter. For example, the following search returns only results that match the term HelloWorld . It excludes results where the case doesn't match, such as helloWorld or helloworld .
Case insensitive SQL SELECT: Use upper or lower functions select * from users where lower(first_name) = 'fred'; As you can see, the pattern is to make the field you're searching into uppercase or lowercase, and then make your search string also be uppercase or lowercase to match the SQL function you've used.
If a written word such as a password is case-sensitive, it must be written in a particular form, for example using all capital letters or all small letters, in order for the computer to recognize it.
You press M-c after you run search.
This will set the case-sensitive flag.
More generally, you can do: C-s C-h b to see all keybindings active during search, in isearch-mode-map.
