In Vim, replace all occurrences of current term under cursor

Question

If you press * in Vim, the editor will search for the next occurrence of the term in the same file. It saves you from having to type out the term.

Is there a quick way to replace the term currently under the cursor with a new one? One character to issue the command, typing in the new term, then Enter.

Answer 1

Just use * and then:

:%s//new value/ 

If you don't specify a pattern, the substitute command uses the last searched one. Depending on the value of gdefault in your configuration, you might need to add a /g modifier to that command.

Answer 2

You can use:

:%s/<c-r><c-w>/new value/g 

where <c-r><c-w> means to literally type CTRL-rCTRL-w to insert the word under the cursor.
