This script is to combat the frustration of navigating all over the place when opening, saving, or changing Explorer folders when most of what you want to do is in ONE FOLDER.
But you have to jump back and forth between apps - say Excel, Outlook, Acrobat, Word - and each has its own idea as to where you should be saving things.
Other people have posted similar scripts, I'm sure. I think Quick Access Popup has a similar feature, but I haven't checked it out.
Ctrl+Win+S: From most open/save dialogs or an open Explorer window, save a folder path.
Ctrl+Win+C: Clear that folder path.
Ctrl+Win+J: Jump to that folder.
Ctrl+Win+Q: Ask the script what folder you have set.
Shift+Escape: Bail out.
Tested so far on Win7, 64-bit, AHK_H 64-bit, 1.1.26.01 (AHK_Hv001). Works with:
[Update 12/16/17] Word, Excel, Powerpoint, Acrobat, Explorer, Thunderbird,Scite4AutoHotkey, Outlook, Notepad, Firefox 57, IE 11, Pale Moon 27 (32-bit), Chrome (from Ctrl+S)
I'm sure many progs will choke on it.
For some reason I called it PersistentSaveFolder. That isn't quite accurate. I couldn't come up with anything else.
