I want to add a custom keyboard shortcut as described here: [The Julia REPL · The Julia Language](https://docs.julialang.org/en/v1/stdlib/REPL/#Customizing-keybindings). I thought it would be quite easy to set an alias for the “home” key:

```julia
import REPL

const mykeys = Dict{Any,Any}(
    # Move to beginning of line
    "^i" => "^a",
)

function customize_keys(repl)
    repl.interface = REPL.setup_interface(repl; extra_repl_keymap = mykeys)
end

atreplinit(customize_keys)

```

this works. Unfortunately, TAB is moving the cursor to the beginning of the line. Any idea what did I do wrong there?

I’m running Julia 1.6.3 on Ubuntu 20.04.

Thank you for your help!
