How to Accept AI Suggestions in Cursor (Tab)

Pressing Tab while an AI-generated autocomplete suggestion is visible accepts it, applying the suggested code — which in Cursor can span multiple lines or even predict several related, coordinated edits, going meaningfully beyond traditional single-token IntelliSense-style autocomplete. **How Cursor's suggestions differ from traditional autocomplete**: rather than just completing the current identifier or a single line, Cursor's underlying AI model can predict multi-line blocks of code, or even suggest edits at other nearby locations in the file that logically follow from the pattern of what you're currently writing, informally described by some users as a 'Tab, tab, tab' flow where accepting one suggestion often immediately surfaces a related next suggestion to accept as well. Ctrl/Cmd+Shift+Enter specifically jumps you to that next predicted location without needing to scroll or search for it manually, keeping the whole chained-edit flow inside the keyboard. **Reviewing before accepting**: the suggested code is shown as a preview (often in a distinct visual style, like grayed-out ghost text) before you commit to it via Tab, giving you a chance to read what's being proposed — this matters more with Cursor's more ambitious multi-line suggestions than with simpler traditional autocomplete, since a longer, more consequential block of generated code deserves more scrutiny before accepting than a single completed word would. **Rejecting instead**: pressing Esc dismisses the current suggestion without applying it, letting you continue typing normally or wait for a different suggestion to appear based on further context. **Partial acceptance**: some autocomplete implementations, including Cursor's, support accepting just part of a longer multi-line suggestion (commonly via a different key combination for 'accept word' or 'accept line' versus the full Tab-based complete acceptance), useful when a suggestion is mostly right but you want to diverge partway through rather than accepting the entire proposed block or rejecting it outright. **A common mistake**: reflexively tabbing through suggestions out of habit, the same way many developers reflexively accept traditional single-token autocomplete without a second thought. Because Cursor's suggestions can be considerably larger and more consequential, building the habit of a half-second visual scan before each Tab press — rather than treating it as a pure muscle-memory reflex — meaningfully reduces the odds of silently accepting a subtly wrong multi-line change. **Related shortcuts**: Esc for rejecting a suggestion, Ctrl/Cmd+Shift+Enter for jumping to the next predicted edit location in a chained suggestion flow, and Cmd/Ctrl+K for triggering a more deliberate, scoped inline edit request rather than relying on the AI's automatic contextual suggestions. **Tuning suggestion aggressiveness**: Cursor's settings expose some control over how eagerly Tab-based suggestions appear and how far ahead they try to predict, which is worth adjusting for developers who find themselves frequently rejecting suggestions — a model tuned to suggest more conservatively, shorter completions can end up feeling faster in practice than one that frequently proposes large blocks that then need review and rejection. **Working in an unfamiliar language**: Tab-based suggestions can be a genuine learning aid when working in a language or framework you're less experienced with, since the proposed completions often reflect idiomatic patterns for that language that you might not yet know to reach for yourself — reading a suggestion even when you're fairly sure you'll reject it can still be a useful, low-cost way to pick up conventions from a codebase or ecosystem you're still getting comfortable in.
