will they be like in which you can switch to 64 bit by going to
application selecting type command Key-I (for get info) and checking box
for 64 bit.
On 10.6, it will automatically launch in 64bit mode (as AFAIK the OS
itself runs at 64bit by default, contrary to what you claim), on 10.5,
it will automatically launch in 32bit mode.
That depends on what machine you're using:

And even this is misleading - by this, my 24" Core 2 Duo iMac should be
able to boot in 64 bit mode, but it won't - even with a 6/4 key start
up; 64 bit boot is not supported by EFI firmware even though it's
running OS 10.6.7.
But my Core 2 Duo MacBook Pro *will* boot into 64 bit mode, but not by
default - it's default is/was 32 bit mode...but I changed that last
night by doing this:

Both machines are running 10.6.7 - you can't really say that 10.6 is "64
bit boot by default" without knowing a bit more about what machine it's
being run on.
To really know you need to launch System Profiler.app and look at the
Software line - it will tell you which kernel is actually booted and in
use (but not which is default).
I have no idea on manual switches as I thankfully can avoid touching the
golden cages from Apple, but I'm told that you can launch SeaMonkey in
32bit mode on 10.6 somehow - you probably know better than me how to do
that. And, as Callek said, best to try it out, the "almost done" last
beta is available for testing!

In the Info window for some apps there's a checkbox for "Launch in 32
bit mode" once you're in 64 bit boot, but I didn't see such for SM
2.0.13 after I booted my MBP in 64 bit mode.
