Lesser-Known Shortcuts for Faster Workflows
Keyboard shortcuts are like secret codes that unlock efficiency, and Merlin has a bunch beyond the basics. Everyone knows Ctrl+M (or Cmd+M on Mac) to summon the Merlin sidebar anywhere. But in 2025, with updates to the extension’s interface, there are nuanced combos and quick-access tricks that intermediate users swear by. I’ll walk you through 7 lesser-known ones, with step-by-step guides and real-world examples tailored for digital marketers, content creators, and productivity buffs. These productivity shortcuts can shave minutes off every task—adding up to hours saved weekly.
- The “/” Slash Command for Custom Prompt Triggers: This is a game-changer for automating repetitive tasks. Step-by-step: First, head to Merlin’s settings (gear icon in the chat window) and create a custom prompt, like “Summarize this page in 5 key bullets with SEO keywords.” Save it as “seosum.” Now, on any site, hit Ctrl+M to open Merlin, type “/seosum,” and press Enter—it applies instantly to the current page. Example: As a digital marketer, I use “/adcopy” on a product page to generate 3 ad variations, complete with calls-to-action. It beats manual prompting every time, especially during A/B testing campaigns.
- Alt + Right-Click Highlight for Contextual Actions: Highlight any text, hold Alt, and right-click to pull up Merlin’s mini-menu for instant rephrasing, translation, or expansion. If it doesn’t appear, ensure “Context Menu” is enabled in extension settings. Step-by-step: Select a paragraph, Alt + right-click, choose “Expand with Merlin” for detailed breakdowns. Example: Content creators, highlight a vague idea in your notes and get a full paragraph—perfect for fleshing out blog drafts without leaving Google Docs.
- Ctrl + Shift + M for On-the-Fly Model Switching: In the Merlin chat, this cycles through models like GPT-4 to Claude for creative tasks or Gemini for factual ones. Step-by-step: Start a query, hit the combo mid-way, and select— no need to restart. Example: Productivity enthusiasts analyzing data might switch to Llama 3.1 for math-heavy queries, ensuring accurate budget forecasts without errors.
- Double-Tap Ctrl+M for Persistent Sidebar Mode: Press Ctrl+M twice quickly to dock Merlin as a sidebar that stays open while you scroll. Step-by-step: On a long article or video, double-tap; it auto-loads page context for ongoing chats. Example: For YouTube research, chat “Explain this section” as you watch—ideal for content creators turning tutorials into custom courses.
- /file Command for Instant Uploads: Type “/file” in the chat to bypass menus and upload PDFs, images, or docs directly. Step-by-step: Ctrl+M, “/file,” select file, then query like “Extract quotes on marketing trends.” Example: Digital marketers uploading competitor reports get instant strategy breakdowns, fueling competitive analysis without extra tools.
- Ctrl + Enter with Chain-of-Thought Prompts: Add “Think step by step” to your query, then hit Ctrl+Enter for reasoned responses (works best with o1 model). Step-by-step: Write the prompt, add the phrase, submit—it forces logical breakdowns. Example: Solving a complex problem like “Optimize my content calendar for Q4″—Merlin steps through audience analysis, trends, and scheduling, super useful for intermediate planners.
- Esc to Minimize and Resume Sessions: Press Esc to tuck Merlin away without closing, preserving your chat history. Step-by-step: Mid-query, Esc; click the toolbar icon to resume. Example: During a hectic day, pause an email draft in Gmail integration and pick up later— a lifesaver for multitaskers.
These shortcuts aren’t just flashy; they’re practical Merlin.ai hacks that integrate into your daily grind. For visual learners, imagine a screenshot here: The Merlin sidebar on a LinkedIn page, with the “/” menu dropdown showing saved prompts like “postidea” and “replygen.”
Pro tip: Customize your own keyboard shortcuts in Chrome’s extension settings (chrome://extensions/shortcuts) for even more personalization. Start practicing on low-pressure sites like news feeds to build muscle memory.
Hidden Settings & Preferences to Personalize Your Experience
Merlin’s settings panel (gear icon or extension popup) is where the real magic happens—full of overlooked options that turn a generic tool into your tailored AI assistant. In 2025, with features like custom bots and brand voice, these AI tool customizations are more powerful than ever. I’ll detail the hidden ones, how to tweak them, and use cases for different users, with step-by-step instructions.
- Custom Prompt Library (Settings > Prompts): Beyond saving basics, build a library of reusable templates. Step-by-step: Click “Add Prompt,” input “Generate a LinkedIn post in my brand voice: [context],” save as “/linkbrand.” Tweak variables for flexibility. Use case: Digital marketers create outreach templates; adjust for cold emails vs. follow-ups, ensuring consistency across campaigns.
- Projects for Knowledge Bases (Settings > Projects): Upload files, links, or notes to create a “vault” Merlin references automatically. Step-by-step: New Project, add your brand guidelines PDF, name it “MarketingHub.” Queries now pull from it. Use case: Content creators build a “ResearchVault” with industry articles—ask “Suggest blog topics based on my vault” for personalized ideas that align with your niche.
- Crafts Mode for Visuals and Code (Settings > Crafts): Enable to generate diagrams, charts, or even React code snippets. Step-by-step: Toggle on, prompt “Create a mindmap for content funnel.” Edit outputs live. Use case: Productivity enthusiasts visualize workflows—e.g., a flowchart for daily routines—then export to tools like Google Slides.
- Privacy and Auto-Save Preferences (Settings > Privacy): Toggle auto-save chats, contextual loading, or data encryption. Step-by-step: Enable “Auto-Load Page Context” for seamless integrations; set notifications for query limits. Use case: For security-conscious marketers, encrypt sensitive client data in projects.
- Model and Tone Defaults (Settings > AI Models): Set per-task defaults, like Claude for writing or Gemini for research, and tweak tones (professional, casual). Step-by-step: Select defaults, test with a sample query. Use case: Intermediate users switch to “Conversational” for friendlier email drafts in Gmail.
These settings make Merlin adaptive. For instance, a beginner might start with default tones, while intermediates layer in Projects for complex tasks. Screenshot idea: The Projects tab open, showing an uploaded PDF and a sample query response pulling from it.
Bonus: In 2025, the new “Custom Bots” lets you chain instructions—like a bot that summarizes, then visualizes data—elevating customizations to bot-level automation.
Custom Workflows & Integrations for Seamless Productivity
Merlin’s strength lies in its integrations, turning it into a workflow hub. It links with Gmail, LinkedIn, YouTube, Google Sheets, and more, but the hacks are in chaining them with shortcuts and settings. Here are 3 in-depth workflow examples, with steps and tips for real users.
- Gmail Outreach Workflow for Marketers: Draft personalized emails using context from threads and Projects. Step-by-step: In Gmail, Ctrl+M, type “/coldout” (your saved prompt), reference a Project for brand voice. Tweak and send. Example: Send 50 customized cold emails daily—Merlin pulls recipient details from LinkedIn tabs, boosting open rates. Tip: Combine with chain-of-thought for “Think through objections” in replies.
- LinkedIn Content Pipeline for Creators: From research to posting. Step-by-step: On a news site, summarize with “/seosum,” then “/linkpost” to generate a post. Use Crafts for an infographic. Post directly. Example: Turn a YouTube video into a thread—transcribe, outline, visualize— all in one flow, growing your audience faster.

These workflows minimize app-switching. Screenshot: Merlin in Gmail, auto-drafting with thread context highlighted.
