Helicase #

Helix-style modal editing for JetBrains products.

Features #

• Helix config ingest: Use your existing Helix bindings and macros with Helicase.
• Native jump label support: Teleport around your files with gw.
• Dynamic minor modes work just like in Helix: m for textobjects, <space> for the leader menu, g for goto — plus any submap you define in your config.
• Differentially tested against real Helix: motion, selection, textobjects, indent / dedent, goto, open-line, and replace all diff against Helix's own command set byte-for-byte in CI.

Installation #

1. Grab the latest Helicase-<version>.zip from Releases.
2. In your JetBrains IDE: Settings → Plugins → ⚙ → Install Plugin from Disk…, then pick the zip.
3. Restart the IDE when prompted.
4. Toggle Helicase on with Ctrl+Shift+H (or set it on by default in Settings → Helicase). The status bar will show the current mode (HEL: NOR / INS / SEL).

From source #

./gradlew :plugin:buildPlugin

The plugin zip lands in plugin/build/distributions/.

Verified product compatibility #

All JetBrains IDEs built on the IntelliJ Platform ^2026.1 should work, Helicase only depends on com.intellij.modules.platform.
