You can map any key you want to the operation of creating a new file in Ranger. This can be done using the
touch command in the Ranger console.
For example, to create a new file when
Ins is pressed, add this to
$ map <INSERT> console touch
Ins is pressed, the
touch is executed at the Ranger console at the bottom and it asks for a filename for the new file.
Tried with: Ranger 1.6.1 and Ubuntu 14.04
