This is an old thread. I spotted my own comment from 2017 above. Here are some more tips I think many don't know:
Need *another* instance of an already running app (like another blank Notepad), Shift +LClick the app on the toolbar to open another instance.
When searching using Google/Bing/Yahoo/etc, enclose compound phrases in quotes. So instead of searching for:
computer parts
...and getting thousands of useless hits that include *anything* containing either word, instead search for:
"computer parts"
...so the only results returned are those containing that exact wording.
You will find keeping your searches to just three "keywords" gives the best results, but a phrase in quotes counts as a single keyword. So a search for:
"Windows 7" "keyboard short cuts" "Libre Calc"
...will return far more accurate search results than the same seven words without quotes.
And on eBay, not only should you use quotes as much as possible, but use the minus sign ("-") before words you wish to filter OUT of your searches (words with quoted phrases too.)
Also on eBay, you can do an OR search by using parenthesis:
("flash drive", "thumb drive") -ssd
...will return searches containing *either* phrase but filter out internal SSD drives.
