Koi bhi key dabaiye aur use full-size, tenkeyless ya 60 % keyboard par light up hote dekhiye, rollover aur event details ke saath — sab aapke browser mein, aur jo aap type karte hain wo aapke device se bahar nahin jaata.
Keyboard Tester
Koi bhi key dabaiye aur use full-size, tenkeyless ya 60 % keyboard par light up hote dekhiye, rollover aur event details ke saath — sab aapke browser mein, aur jo aap type karte hain wo aapke device se bahar nahin jaata.
Keys isi tab mein sirf on-screen keyboard ko light up karne ke liye paDhi jaati hain. Aap jo kuch dabaate hain wo na store hota hai na kahin bheja jaata hai, aur page reset ya band karte hi results gayab ho jaate hain.
Keyboard Tester ek poora on-screen keyboard banata hai aur har key ko dabaate hi light up kar deta hai, isliye dead switch, atki hui key ya ek dabaane par do baar chalne wali key kuch hi second mein pakDi jaati hai. Key register hote hi green ho jaati hai, aur ek counter batata hai ki aapne keyboard ka kitna hissa jaanch liya hai — full-size layout par 104 keys, tenkeyless par 87, aur 60 % board par 61. Kai keys ek saath dabaye rakhiye to rollover counter wo sabse zyada keys record karta hai jo aapke keyboard ne ek saath report ki, aur ghosting isi se pakDi jaati hai. Ek detail card batata hai ki aakhri key ke liye browser ko kya mila: key, code, purana keyCode, location, modifiers aur repeat flag. Matching physical key ki position se hoti hai, isliye yeh kisi bhi language layout ke saath chalta hai. Sab kuch isi tab mein hota hai, aur jo aap type karte hain wo na store hota hai na bheja jaata hai.

Physical key se match karta hai, isliye AZERTY, Dvorak, Cyrillic aur doosre layouts sahi keycap ko light up karte hain
Test ke dauraan Tab, F-keys, Backspace aur Space ko page par kaam karne se rokta hai, lekin Ctrl/⌘ + W, T, N, R, L ya F12 ko kabhi block nahin karta

Common errors aur troubleshooting
Ek key kabhi green nahin hoti. — Pehle dekhiye ki badge par Capturing keys likha hai — agar start overlay wapas aa gaya ho to keyboard par dobara click kijiye. Phir bhi grey rahe, to key koi signal nahin bhej rahi: keycap ke neeche saaf kijiye, doosra USB port ya alag keyboard laga kar dekhiye, aur dobara jaanchiye.
Fn, volume ya doosri media keys par kuch nahin hota. — Un keys ko keyboard ke andar ya operating system sambhalta hai, isliye browser ko wo aksar milti hi nahin. Iski jagah un keys ko jaanchiye jinhe wo badalti hain, aur Also detected ke neeche AudioVolumeUp jaise naam dhoondhiye.
Max keys at once 2 ya 3 par ruk jaata hai, jabki keyboard ko isse zyada sambhalna chahiye. — Budget membrane keyboards mein keys ke beech wiring saajha hoti hai, isliye kuch combinations ghost ho jaate hain. Switches ko kharab maanne se pehle alag keys, hub ki jagah seedha USB port, aur wireless dongle ki jagah wired keyboard aazmaiye.
Alt+Tab jaise shortcut ke baad page jawab dena band kar deta hai. — Operating system ne wo shortcut page ke dekhne se pehle hi le liya, jisse keyboard focus bhi chhoot jaata hai. Dobara capture shuru karne ke liye keyboard area par click kijiye, ya kaam poora hone par chhoDne ke liye Esc teen baar jaldi-jaldi dabaiye.
Aksar pooche jaane wale sawaal
Main Keyboard Tester se dead key kaise dhoondh sakta hoon?
Har key ek baar dabaiye aur use green hote dekhiye. On-screen keyboard par jo key grey reh jaaye, ya Keys not tested yet mein dikhe, usne koi signal nahin bheja. Use kuch baar zor se dabaiye; agar wo sirf kabhi-kabhi chalti hai, to switch ya uska contact ghis raha hai.
Keyboard Tester ke max keys at once counter ka kya matlab hai?
Yeh wo sabse zyada keys hain jo browser ne ek hi pal mein dabi hui dekhi, yaani aapke keyboard ka rollover. n-key rollover wala keyboard har key report karta hai; saste keyboards chhah ya usse kam par ruk jaate hain, aur kuch combinations seedhe block ho jaate hain, jise ghosting kehte hain. Aur zyada keys dabaate rahiye aur dekhiye ki counter kahan baDhna band karta hai.
Fn aam taur par keyboard ke apne firmware ke andar kaam karti hai, aur volume, brightness aur play keys ko operating system sambhalta hai, isliye page ko sirf unhi ke baare mein bataya jaata hai jo aam key events mein badal jaati hain. Jab koi laptop media key report karta bhi hai, to uska naam bane hue layout par nahin, Also detected ke neeche dikhta hai.
Key value wo akshar ya action hai jo press se bana, aur wo layout aur Shift ke saath badalta hai, jaise a ya A. Code physical key ka naam batata hai, jaise KeyA, aur layout ke saath kabhi nahin badalta; on-screen keycap isi se light up hota hai. keyCode ek purana number hai jo browsers ab bhi bhejte hain par jo deprecated hai.
Kya Keyboard Tester Mac keyboard ke saath chalta hai?
Haan. Command, Meta ke roop mein dikhta hai, jo Win keycap par dikhaya jaata hai, aur Option, Alt ke roop mein dikhta hai. macOS Command dabaye rakhne ke dauraan dabayi gayi keys ka key-up chhoD deta hai, isliye jab aap Command chhoDte hain to tester unhe release kar deta hai. Caps Lock ek chhoti si jhalak ki tarah light up hota hai, kyunki kuch systems use sirf tab report karte hain jab wo on ya off hota hai.
Kya Keyboard Tester mein main jo kuch type karta hoon wo kahin bheja jaata hai?
Nahin. Key events isi tab mein sirf keys ko light up karne aur log bharne ke liye paDhe jaate hain; text na store hota hai na bheja jaata hai, aur page reset ya band karne par results hat jaate hain. Aapke device par sirf yeh yaad rakha jaata hai ki aapne kaunsa layout chuna.
