KeyFast for After Effects
KeyFast v1.2 for After Effects
The Ultimate Keyframe Navigation and Timeline Speed Tool for After Effects
Download KeyFast v1.2 today. Consequently, you can navigate between keyframes instantly and dramatically speed up your animation workflow with a comprehensive suite of keyboard-driven shortcuts. Because professional animators spend countless hours jumping between keyframes, selecting properties, and adjusting timing, having access to a dedicated navigation tool is absolutely essential. Nevertheless, After Effects’ native keyframe navigation is limited, often forcing you to click through the timeline manually or use awkward multi-key shortcuts. Fortunately, KeyFast eliminates this bottleneck completely. Moreover, it provides a full set of intuitive hotkeys for jumping to the next or previous keyframe, selecting keyframes across layers, and navigating complex animations without ever touching the mouse. In short, you can work faster, stay focused, and keep your hands on the keyboard where they belong.
Instant Keyframe Navigation and Selection
The core of this script lies in its powerful, keyboard-first approach to timeline navigation. For instance, you can jump to the next or previous keyframe on a selected property with a single keystroke, eliminating the need for tedious timeline scrubbing. Furthermore, the script allows you to select all keyframes at the current time across multiple layers, making it easy to make synchronized adjustments. Additionally, you can navigate between keyframes on different properties without losing your selection. Since the entire system is designed around speed, you can move through even the most complex animations with fluid, uninterrupted precision. Consequently, your animation workflow becomes significantly faster and more intuitive.
Advanced Multi-Layer Keyframe Management
Professional animations often involve dozens of layers and hundreds of keyframes. Therefore, KeyFast includes powerful tools for managing keyframes across multiple layers simultaneously. For example, you can jump to the next keyframe across all selected layers, ensuring you never miss a timing cue. Furthermore, you can select keyframes on specific properties across multiple layers, making it easy to adjust timing consistently throughout a composition. Additionally, the script supports navigating keyframes in precompositions, allowing you to work seamlessly within nested structures. Thus, you maintain complete control over even the most complex animation timelines.
Customizable Hotkeys and Workflow Integration
Every animator works differently, and KeyFast respects your personal preferences. Accordingly, the script includes a comprehensive hotkey customization system. For instance, you can assign your own keyboard shortcuts to any KeyFast function, ensuring the tool adapts to your existing workflow rather than forcing you to learn new commands. Furthermore, you can create multiple hotkey profiles for different types of projects or tasks. Additionally, the script integrates seamlessly with After Effects’ native keyboard shortcuts, so you can use both without conflict. Consequently, KeyFast becomes a natural extension of your existing animation process.
Perfect for Character Animators, Motion Designers, and VFX Artists
This script is particularly well-suited for character animators who need to navigate complex rigs and keyframe-heavy performances. Similarly, motion designers working on kinetic typography and multi-layer compositions will appreciate the speed and precision KeyFast provides. Additionally, VFX artists and compositors can use the tool to quickly navigate animated elements within complex shots. Ultimately, KeyFast v1.2 accelerates your entire animation and post-production pipeline.
System Requirements and Compatibility
KeyFast v1.2 supports After Effects versions 2022, 2023, 2024, 2025, and 2026 on both Windows and macOS operating systems. The script is available as a standard JSX file for easy installation. You will need a standard workstation with at least 8GB of RAM.
