Editing and folding
- Move Caret to Code Block Start / End with Selection, Auto-Indent Lines,
Move Element Left / Right (swaps call arguments, parameters and list
entries).
- Fold Code Block folds the {...} block around the caret; Expand to Level
and Expand All to Level 1-5.
- Custom folding regions (//region, #region, <editor-fold>) fold to their
description; Navigate > Custom Folding lists them.
- Error Description shows the problems at the caret; Next / Previous
Highlighted Usage steps through usage highlights.
- Editor tooltips stay below the editor's top edge, so hints on the first
lines no longer hide under the tab bar.
Navigation, project and run
- Navigate > File Path lists the file and its folders to reveal in the file
manager.
- Copy... (F5) opens the Copy dialog for the selection or the open file; the
project view's Refactor submenu gets Copy File.
- Debug... chooses a configuration to debug; Quick Evaluate Expression shows
the selection's value in an expandable hint.
- Inspect Current File runs the inspection without the scope dialog.
- Surround with Live Template lists only $SELECTION$ templates; Java gets
Callable, read / write lock and iterate templates.
Windows
- Stretch the active tool window left / right / up / down, Restore Default
Layout, Go to Next / Previous Splitter, Close Active Tab on a second key,
Stop Background Processes.
All actions have default shortcuts in both keymaps, VS Code preset entries,
main menu items and Chinese translations.
Project view and Keymap settings
- Project view Options: Sort by Name / Type / Modification Time (also in
Find Action).
- Settings > Keymap: Add Mouse Shortcut records a side-button click with
modifiers and checks conflicts like keyboard shortcuts.
- Folding: Expand to Level / Expand All to Level 1-5.
The IDE you know, rebuilt in Rust.

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
