Greek transliteration resources

A quick way to do an English-to-Greek transliteration in Logos is go to into the Bible Search Tab, type g:, and then without any following space start typing the word phonetically with English letters. Logos will soon drop down a menu of words in Greek that match what you've typed so far. Sooner or later you'll see the one you're looking for, which you can select and press Enter. Then just copy the Greek text from the Search box and voila!

EDIT: For Greek to English transliteration, there are different systems, so "properly and uniformly" depends on which system you're using.

I found this web tool that does one of them, but it only does Classical Greek and Modern Greek; not sure if Koine Greek differs from Classical enough to affect the transliteration rules. I am pretty new to Greek too.

What you suggested with Logos is what I do now. I was just wondering how someone in let's say academia does it when they write a paper and have to enter in the Greek words. 

One option is have a Koine Greek unicode keyboard installed on Windows that you switch to when you want to write Greek in a document...

I'm not someone in academia but when I need to enter Greek words in Microsoft Word (as for example when I'm working on a transcribing a that includes some Greek text to make a Personal Book), I use the Insert Symbol dialog box:

There are two sections in the Unicode character set for Greek, and I have to switch back and forth between them a lot when entering accented Greek text, which is a pain. I wish there were a simpler way:

Oh, but there is a simpler way! I had forgotten all about this, but Logos created an internal tool for their own employees to use, called Shibboleth. They have made it freely available to users (http://www.logos.com/shibboleth) with no guarantees or support. It's pretty nice:
