Just click on the Search in the forums box then click on enter of your keyboard.
To be precise, it goes like this: 1. Click in the 'Search' box at the bottom of the forum - this gives the 'Search' box the input ''focus''; 2. Type your search term(s) into the 'Search' box; 3. This is where it is counter-intuitive: there is no 'Go' button for the search; do not touch the 'Jump To' drop-down list, and do not click on the 'Go' button - just press your 'Enter' key while the 'Search' box still has the focus.Then you will get the results as shown! 8-) It really could be done much better.
