I found that we could call a menu while a file is selected in drag'n drop mode. Could be a useful feature to have the possibility to "open files with" a selected items in this case ?
... tutorial for making Radial Menu skin ...
Good idea, I'll try to do it when I'll have more time.
P.S. I'm glad to see you're back to AHK forum!
... I could do that, if it was okay with Learning one ...
I'm absolutely OK with that; everybody is welcome to help & contribute
... radial menu - examples of usage - how others use RM ...
Uh.... I use it for many things - I'll try to be short...
I use radial menus to open frequently used files (apps, docs, scripts) and folders.
For opening less frequently used stuff, I use Everything Search Engine; in my setup, Win+w hotkey displays Everything search window.
I have many items in radial menu which execute custom functions: add a bookmark in MS Word, go to bookmark, print a document, download some data, check e-mail acconts, auto-fill fields in forms, play music from a playlist, insert text, etc.
I have context sensitive radial menus for SciTE4AutoHotkey, and Paint.net, which allow me to quickly select drawing tools, call dialogs, do effects, insert text...
My RM automatically launches (if they aren't already launched) MS Word, Everything search engine, Magnifier, TTS engine with 2 voices; English and Croatian, VirtuaWin and ScreenClip2Win.
I have hotkeys to Execute selected text (RMApp_ExecuteSelectedText()), to do ScreenClip2Win, copy plain text, invert screen colors, read selected text (TTS), change volume.
I have one special hotkey - CEDILLA (SC029) which operates in this way: when I press & hold it for 0.3 second or more, it displays a radial menu where I can select what this hotkey will do (some sort of setting dialog), and when I press & release it briefly (for less that 0.3 second), it does what I previously told it to do. In short; press & hold = set, press = do it.
I use mouse gestures to manage virtual desktops (I use VirtuaWin and have 3 virtual desktops setup), to resize, arrange and close windows, call some additional radial menus, get full paths of selected files & folders, and run selected file in Windows Explorer with predefined app; usually to run a Script.ahk with Radial menu.exe (renamed AutoHotkey.exe) on computers which don't have AutoHotkey installed.
I use Navigator to quickly navigate to frequently used folders in Windows Explorer and in Open/Save dialog windows in many apps.
I use a few hotstrings mainly to insert dates in specific format, signatures, and my e-mail address.
I use "My NCHITTEST" to toggle always on top state of the window, and sometimes to change window's transparency.
I use OnRMShowHotkey event (when LButton and RButton are down) to easily highlight selected text in MS Word and Outlook.
There is more what I do with RM, but stuff mentioned above is probably the most important...
It definitely speeds up my workflow and makes it more comfortable, enjoyable and easier.
