The above statements give you some info on mapping keywords. However, since you are working recording in the Manual mode, you probably should not be “mapping” your new keyword method to some other default method, yet. Read kazurayam’s response on “mapping” on your other question on this topic.
Edit: you can easily use “Search and Replace” after the fact with CRTL + F.

Start by reading the below link to create your custom keyword (don’t forget to put the phrase @Keyword above your method). Once you have created your custom keyword(s), you will be able to select it/them from your list you make. The below link tells you how.
