I spent most of my Saturday at an Accordance seminar. A bit of background: I purchased the program about a year and half ago after using BibleWorks and Libronix for a few years (I converted to mac and won’t go back).
One of the newer features in Accordance has potential but left me disappointed. When hovering over a word with the cursor, pressing and holding the command key can now bring up a lexicon entry in the instant details window. The problem: There is no scroll feature in this window, so you see as much of an entry as will fit in the window. This makes most of BDAG useless as far as the instant details window goes. For the time being, I’ve set BDAG as a separate window to the right of my main workspace. To toggle from one entry to the next, I must triple click a word. BibleWorks still has the edge here: When I hover over a word, I instantly see a lexicon entry or a plethora of resources regarding the word and or verse reference. It appears that Accordance is working toward a similar capability.
Accordance is not without its advantages, though. More on this later in the week!
Update: I’ve included the following screenshots from BW (cf. David’s comment and my response). Click to enlarge.
