This is most frustrating thing that I experience when I encounter Solaris bash prompt: the Home, End and Delete keyboard keys will not work because for some reason Solaris doesn’t understand them as useful keys. But there is the way to enable those keys!
Add following lines to your ~/.bashrc file:
# home key
# del key
# end key
# pgup key
# pgdn key
Save and source file. Now keys will work as they should.
