Kartu answered a view inches above. There will/can/could be the possibibility for custom dic's in a couple of months.

I for my part use this method:

I have a dic (PDF) on my reader. When searching a word I'll open it with a single tap onto the right upper corner of the screen from within the book I'm reading. I have to search for the word manually. Switching back to the book I'm reading goes the same way - tapping onto the right upper corner of the screen.

I use my own cutom build PRS+ for my PRS350 which makes that possible. You could give it a try (have a look at my signature at the bottom of this posting).

To make it function you would have to

1) install my custom firmware ('ZORK-Edition')
2) use a PDF-file as dic
3) rename the dic to DIC.pdf
4) copy this file onto the reader in /Books/DIC.pdf (into the folder named 'Books')
5) assign the right action to the 'single tap' in PRS+ options

I'm working on the possibility to use at least 2 different dic-files (PDF and EPUB)
