Chord symbols

[pdxdjazz]

When entering chord name, I punch in the main letter (C , D , etc....)
Then the next screen shows up with a lot of chord attributes (7, -7, 7sus, etc....)
Many of them are obvious as they use letters and numbers. But some of them use special symbols.
Can someone explain me the meaning of these 3 symbols:

1) the delta symbol
2) the circle 'o',
3) the 'o' with a '/' across

I appreciate incoming help.

Δ = major7
O = diminished
ø = half-diminished m7b5

thank you.
I'm a bit confused, though.
What's the difference between ^ and ^7 then?
I mean, if ^ is maj7 what's ^7?

thanks in advance.

All different ways of writing the SAME chord. (1,3,5,7)
The iRp player recognizes them all.

Some folks have strong opinions about which they prefer.
