Hintium

Vimium-style keyboard hint navigation for all JetBrains IDEs.

Press a shortcut and every actionable element in the IDE lights up with a letter hint. Type the letters to click it — no mouse needed. Works across the entire IDE, not just the editor.

Features

• Hint overlay on everything — Buttons, tabs, tool windows, trees, lists, tables, editor tabs, navigation bar, terminal buttons, and more all get letter hints.
• Home-row-first hints — Hint characters start from a s d f g h j k l so your fingers barely move.
• QMK-style combos — Press two keys simultaneously to trigger any IDE action or synthesize a keypress. Combos are order-independent (D+K = K+D) and work even while hints are active.
• Customizable appearance — Adjust hint background color, matched-character color, text color, font size, and opacity to match your theme.

Installation

Install directly from the JetBrains Marketplace:

1. Open Settings > Plugins > Marketplace
2. Search for Hintium
3. Click Install and restart the IDE

Usage

Hint navigation

1. Press the activation shortcut to show the overlay (default: Ctrl+Alt+Shift+Space, customizable in Settings > Keymap).
2. Letter hints appear on all actionable UI elements.
3. Type the hint letters to activate that element. Matched characters highlight as you type.
4. Press Escape or the activation shortcut again to dismiss.

Combos

Combos let you trigger actions by pressing two keys at the same time (within a configurable time window). Enable them in Settings > Tools > Hintium.

Default combos (when enabled):

Keys	Action
D + K	Toggle hint overlay
F + J	Escape

Each combo can either:

• Execute an IDE action — chosen from a searchable list of all registered actions.
• Synthesize a keypress — sends a keypress (with optional modifiers) to the OS.

Configuration

All settings are under Settings > Tools > Hintium:

Setting	Description
Hint colors	Background, matched-character background, and text color (with opacity)
Hint font size	Size of the hint label text
Enable combos	Toggle the combo system on/off
Combo term	Time window (ms) for recognizing simultaneous key presses
Combo table	Add, edit, or remove combos — map key pairs to IDE actions or synthesized keypresses

Compatibility

Works with all JetBrains IDEs — IntelliJ IDEA, WebStorm, PyCharm, GoLand, CLion, Rider, RubyMine, DataGrip, Android Studio, and others.

Requirements: Java 17 • IntelliJ Platform 2024.3+
