Tip 1 — Use Keyboard Shortcuts
Press Ctrl+Enter (Windows/Linux) or Cmd+Enter (Mac) to trigger the main action in Regex Tester without reaching for the mouse. This speeds up repetitive tasks significantly.
Tip 2 — Select All with Ctrl+A
After the output is generated, press Ctrl+A or Cmd+A inside the output box to select all text instantly before copying. This is faster than triple-clicking or using drag selection.
Tip 3 — Use Multiple Browser Tabs
Open Regex Tester in multiple browser tabs to compare different inputs or settings side by side. Each tab maintains its own independent state.
For developers, opening the browser console alongside Regex Tester lets you inspect the raw output and run additional processing with JavaScript.
Tip 5 — Clear Cache for Fresh Results
If you notice unexpected behaviour, try a hard refresh (Ctrl+Shift+R) to clear the browser cache and reload the latest version of Regex Tester.
Tip 6 — Mobile Workflow
Add Regex Tester to your mobile home screen via the browser's "Add to Home Screen" option. This gives you instant one-tap access on your phone or tablet.
Tip 7 — Share Results via URL
For some tools, the current state can be shared via the URL. Check the address bar after entering input — if the URL updates, you can share it directly with colleagues.
