= ... and replace =

The command bound to ''F5'' first checks if the search string is found at the
current cursor position and if it is found it replaces it with the value of the
replace string. The replace string can be set by pressing ''Foenix+r''. As usual
this command can be aborted by entering an empty string when prompted. As the
default replace string is the empty string you should make sure that a proper
replace string is set before using the ''F5'' command. The command does nothing
when no search string is set.

To sum it up: In case you want to perform a search and replace operation you
should first set the search string and after that the replace string. You then
can then use ''F3'' and ''F7'' to search and if you want to replace a found
occurrance you press ''F5''.
