Trouble with keymap.edn

Hi all.
I download the keymap_linux.edn file, and insert that strings in that …
[“Alt+J” :left]
[“Alt+I” :up]
[“Alt+L” :right]
[“Alt+K” :down]
[“Alt+U” :prev-word]
[“Alt+O” :next-word]

Hotkeys - “Alt+U” and “Alt+O” work well. But “Alt+J”, “Alt+I”, “Alt+L” and “Alt+K” does not.

What can I do with it??
