No documentation for 'somecharacters' in specified packages and libraries: you could try 'help.search("somecharacters")'

I'm looking for some advice. I'd like to hack my source code in such a way that the empty prompt line above is "pre-filled" with the suggested command. In effect, this would make it unnecessary to copy-paste (or type)
help.search("somecharacters")

If I did not want to execute the suggested command, I would Ctrl-c the pre-filled line.

Alternatively, the hack could implement a query, as in:

> ?somecharacters

No documentation for 'somecharacters' in specified packages and libraries: you could try:

0 - help.search("somecharacters")
1 - RSiteSearch("somecharacters")
2 -  apropos(somecharacters)
3 - etc .....

<enter> - no action

.... in which case, typing 0, 1, 2, 3, ... and <enter> would issue the corresponding command, or would pre-fill a command line with the corresponding command (which could then be edited).

Alternatively, the hack could add the recommended commands to the command history, in which case I could use the up/down arrows to navigate to them.

I suppose it might be the case that a similar feature is already part of R, and that I am just not aware of it. As a newbie, I spend most of my time searching/reading documentation.

Any comments regarding the possible alternatives that I've mentioned, or offers of your own alternatives, would be appreciated, as would be suggestions or mini-outlines for implementing the hack.

TIA,
Mike
