/* 
Date/time hotstrings

If you want the date/time in the format yyyymmdd_hhMM on 10/29/2022 at 10:37 AM, type:
dtm

You should see:
20221029_1037 

To add your own:
1. Decide on your hotstring (e.g. tst)
2. Add your hotstring to the top of the hotstring list (line 18):
:?*:tst::
{remaining hotstrings}

3. Add your hotstring with a date/time mask to the DateTimeFormats list (insert at line 37, for example)
,"tst":"h:mm tt"

4. Reload the script
5. Test your hotstring:
If it's 10:43 AM, for example, and you type:
tst
You should see:
10-43 AM
