bug: ctrl-shift-tabbing to previous editor view detaches editor tab

Hi,

I'm on Win10 and I have eclipse default keymaps set with a custom keymap setting "select next tab" to ctrl-tab and "select previous tab" to ctrl-shift-tab. This matches the tab cycling experience in many apps including most web browsers.

It works great, however there is one weird little bug I noticed:
When hitting ctrl-shift-tab when also moving the mouse (even a very small amount) the editor tab will detach into its own window. It seems like somehow the mouse movement plus the ctrl-shift-tab keys pressed at once triggers the detach window command (which is normaly evoked by itself through shift-f4). It's kinda annoying when you are cycling through tabs really fast, you have to be conscious not to move the mouse at all when going backwards. I looked to disable the shift-f4 shortcut, but there doesn't seem to be a way to do this in the keymap prefs.

Anyone else seen this or have a solution?

As far as I know, there is no action to detach editor window, see https://youtrack.jetbrains.com/issue/IDEA-88275 .

Not sure what triggers this behavior, probably the way mouse moves are interpreted with certain modifier keys.

Anyway, please report this issue at http://youtrack.jetbrains.com/issues/IDEA .

Thanks. I've reported the issue. Hitting Shift-F4 does detach the window, however it doesn't show up in the keymaps prefs so can't be changed or disabled.
