1. Check out the R reference card at http://www.rpad.org/Rpad/Rpad-refcard.pdf . There are also several others available from the CRAN website.
2. Check out TINN-R, a Windows text/R code editor that integrates the above and provides function "tips" inline to give the syntax of many R functions. 3. ?help.search 4. ?RSiteSearch (or search CRAN directly using Jon Baron's search engine). These do not eliminate the problem, but hopefully mitigate it. Given that there are several thousand R functions spread among hundreds of packages at at least three separate repositories (CRAN, BioConductor, and Omegahat), it's clearly a nontrivial issue. But that's why Google and other search services are multibillion dollar companies.
