streamlit-shortcuts 0.1.8

Streamlit keyboard shortcuts for your buttons.

Streamlit Shortcuts

Streamlit Shortcuts allows you to easily add keyboard shortcuts to your Streamlit buttons.

Installation

pip install streamlit-shortcuts

Example

import streamlit as st
import streamlit_shortcuts

def delete_callback():
    st.write("DELETED!")

streamlit_shortcuts.button("delete", on_click=delete_callback, shortcut="Ctrl+Shift+X", hint=True)

⭐ NEW in v0.1.5: Support for args and kwargs

import streamlit as st
import streamlit_shortcuts

def delete_callback(item_id, user="anonymous"):
    st.write(f"Item {item_id} DELETED by {user}!")

streamlit_shortcuts.button(
    "Delete",
    shortcut="Ctrl+Shift+X",
    on_click=delete_callback,
    hint=True,
    args=(42,),
    kwargs={"user": "admin"},
    type="primary"
)

This creates a primary Streamlit button labeled "Delete" with the shortcut "Ctrl+Shift+X". When clicked (or activated via shortcut), it calls delete_callback(42, user="admin").

🥱 Old

import streamlit as st
from streamlit_shortcuts import add_keyboard_shortcuts

def delete_callback():
    st.write("DELETED!")

st.button("delete", on_click=delete_callback)

add_keyboard_shortcuts({
    'Ctrl+Shift+X': 'delete',
})

The 'Ctrl+Shift+X' combination will trigger "Another Button".
