IntelliJ or WebStorm keymaps don't work in Debian 9

Question

I installed WebStorm and IntelliJ plugin for it.

I can't use any shortcuts in WebStorm such as Ctrl+Alt+S for settings. I double-check that VIM-Emulator is enabled in Tools → VIM-Emulator and looked in Editor → Vim-Emulation tab, and change shortcuts what i need to VIM. Nothing happens even after restarting WebStorm and nothing after change handler to IDE also.

Reinstalling IntelliJ plugin give zero effect. Please help. I need my shortcuts from Windows such as Ctrl+C

Answer 1

Please make sure that

1. Ctrl+C and Ctrl+V in your current keymap selected in Settings | Keymap mean Copy and Paste
2. You don't have any key mappings in your ~/.vimrc
3. Handlers for conflicted Ctrl+C and Ctrl+V are set to IDE in Settings | Editor | Vim Emulation
