In fish it would immediately expand to dir2.
If you have “Dir1” and “DIR2” and you type “cd d”, your prompt will look like in the next picture. Fish automatically transforms “d” into “D”, because there is no dir starting with the lowercase “d”.
On a subsequent <TAB> you’ll get a list of dirs matching your prompt so far in which you choose an entry with the cursor key and enter it with the enter key.
