Easy and fast access to often executed commands that are very long and complex.

When using reverse-i-search you have to type some part of the command that you want to retrieve. However, if the command is very complex it might be difficult to recall the parts that will uniquely identify this command. Using the above trick it's possible to label your commands and access them easily by pressing ^R and typing the label (should be short and descriptive).

UPDATE:

One might suggest using aliases. But in that case it would be difficult to change some parts of the command (such as options, file/directory names, etc).
