Ctrl+A, Ctrl+Z, Ctrl+Y Key takes more time

Description

Ctrl+A, Ctrl+Z, Ctrl+Y Takes More Time.

If I press Ctrl+A, It takes more time to select, in the same way Ctrl+Z and Ctrl+Y keys are also taking time to undo and redo.

Where and in which code it has to be fixed to make it work properly?

Hi @manojrampur-tiger! I'm Dosu and I’m helping the plate team.

The slowness with Ctrl+A, Ctrl+Z, and Ctrl+Y is usually tied to how Plate and Slate handle keyboard shortcuts and document state. Undo/redo (Ctrl+Z, Ctrl+Y) are managed by Slate’s history plugin, mainly in with-history.ts and history.ts, and triggered by hotkey logic in editable.tsx—performance drops if your document is large or plugins are heavy, since undo/redo must snapshot and restore the whole state each time slate-history.ts, editable.tsx.

Ctrl+A (select all) is handled by the browser’s contenteditable, but if your document is large or deeply nested, selection can lag. Plate does not override this, but plugins that add selection logic (like block selection) can impact performance. Recent Plate updates introduced optimizations for block selection, e.g. BlockSelectableProvider and useBlockSelectableStore, but if you have a lot of plugins or custom onKeyDown handlers, these can slow things down #3597.

To improve performance, check for heavy or misconfigured plugins, custom keyboard handlers, or large document structures. Try profiling with browser devtools to see where the bottleneck is. If possible, isolate plugins or reduce document size to pinpoint the cause discussion.

If you need to dig deeper, focus on optimizing plugin logic and document structure, or look into Slate’s history stack management for undo/redo.

The slowness with Ctrl+A, Ctrl+Z, and Ctrl+Y is likely due to how Plate and Slate handle selection and undo/redo, especially with large documents or complex tables.

• Ctrl+A (select all) is handled in Plate’s SlateReactExtensionPlugin via an onKeyDown handler, but the actual selection logic relies on Slate’s selection transforms. If your document is large, the selection operation can be slow because it traverses the entire node tree. You can find this logic in Plate’s SlateReactExtensionPlugin and hotkeys.ts for shortcut detection, but the heavy lifting is in Slate’s transforms and selection logic see source.

• Ctrl+Z (undo) and Ctrl+Y (redo) are managed by Plate’s HistoryPlugin, which simply wraps Slate’s withHistory function. The actual undo/redo logic is in Slate’s history stack, which stores and replays batches of operations. If your history stack is large (lots of edits, big documents), these operations can lag see source.

Performance can also be affected by plugin misconfiguration, plugin order, or custom onKeyDown handlers that interfere with Plate’s default logic see source. For large tables, consider using a "void table node with lazy loading" pattern to avoid rendering all rows at once see source.

To improve performance, profile your document size, check for unnecessary plugins or custom handlers, and consider optimizing how large tables or blocks are rendered. If the bottleneck is in Slate’s core transforms or history, deeper optimization may be needed there.
