create a snippet with title: "_rdtsc" no need to enter shortcut or description
in the left panel try to scroll to the snippet using keyboard. start by typing _ ,then r ,then d ,then t etc. when I type _ all the snippet get selected automatically. This is not expected.
Also, it is great to see vax investing in improving their snippet editor. I'm wishing they add a folders capability to it so that we can arrange our snippets properly.
It is because you must hold shift key down during typing of underscore. The behavior you see is default behavior of lisbox in WPF, so all I could do is to disable it using IsTextSearchEnabled property, but it is certainly not what you want. Same is happening when you press shift + any letter, it selects all snippets from the current position to the first snippet starting with letter you pressed.
I will look, what I can do with it and try to find some workaround.
