Thanks y'all for opening this can of worms of inspiration!!!
How many Everything buttons on your toolbar is too many?? 
I have a drop down menu with the example searches from this tread in it.
Then in my custom apps tool bar i have this...
the first 3 are also in my context menu as well
There's a Everything Icon Pack shared on their forums for the custom colored icons.
The commands I'm using and what the button does...
I will add I have most of these hotkeyed to an E combo so I don't actually have to use the mouse to get to the toolbar or context menu.
NOTE!: If anyone wants to use these buttons, the program path is set of the default location of
Everything 1.5a. If you have installed elsewhere you'll have to update that.
1. Searches the selected items name, folder or file with extension in everything.
a fast dup search
@nodeselect
@disablenosel
"C:\Program Files\Everything 1.5a\Everything64.exe" -s "{file$}"
2. Searches the Active Parent Directory in your lister in everything.
e.g. if your in your Downloads folder its sends "C:\users\%profile%\Downloads" to everything, essentially this is flatview but in the everything window
@nodeselect
@disableifpathr:^coll://
cd "C:\Program Files\Everything 1.5a"
"C:\Program Files\Everything 1.5a\Everything64.exe" {sourcepath$}
3. Searches\views a selected folder in everything.
this is everything default context menu option when you right-click a folder, thou here i dopus controlling my context menu over the windows
@dirsonly
@disablenosel:dirs
@nodeselect
cd "C:\Program Files\Everything 1.5a"
@async:"C:\Program Files\Everything 1.5a\Everything64.exe" {filepath$|noterm}
4. Search the Windows System Index for Content using Everything's interface with Dopus!
This button sends a search string to everything which then sends it back for viewing in Dopus in a New Tab
NOTE!!! This button requires Everything 1.5a. The syntax is not supported in v1.4
I've shared this button in its own thread.
go /profile NEWTAB
Find QUERYENGINE=everythingglobal QUERY si*:{dlgstring|Search Content in Windows System Index via Everything \n -- no quotes will find all words \n -- Add "quotes to search a phrase" \n -- Advanced Syntax E.g... \n -- ext:txt "your phrase" \n \n Search System Index For...}
5. Searches for a selected file or folder name with no extension in Predefined Directory.
This button will not work for you out of the box. To use it replace "X:\XXX" in the button with "X:\a path\you want to search" . It will always send the query to this one directory.
In my case it's a directory of file listings for offline external backup drives that I don't keep plugged in.
@disablenosel
@nodeselect
"C:\Program Files\Everything 1.5a\Everything64.exe" -s {file|noext} "X:\XXX"
and... last but not least...
6. Open Everything Search Item In New Tab
This button only appears when you're inside a Dopus File Collection, while viewing an internal Everything Search. It will open the the directory of selected item in a New Tab keeping your search untouched.
