Emergency Zero-Software Presentation Guide for India
कई बार जब हम किसी दूसरे कॉलेज में सेमिनार देने जाते हैं या किसी क्लाइंट के ऑफिस पहुंचते हैं, तो वहां के कंप्यूटर में माइक्रोसॉफ्ट ऑफिस नहीं होता या लाइसेंस एक्सपायर हो चुका होता है। ऐसे में PPTMaker का ऑनलाइन व्यूअर आपकी प्रेजेंटेशन को बिना किसी सॉफ्टवेयर के सीधे ब्राउज़र में चला देता है।
Instant F5 Full-Screen Projection
बस "Launch Slideshow" पर क्लिक करें और स्क्रीन पर बिल्कुल पावरपॉइंट जैसा अनुभव पाएं। ब्राउज़र की कोई पट्टी या टैब दिखाई नहीं देगा।
Arrow Key & Click Navigation
कीबोर्ड के Arrow Keys (दाएं-बाएं तीर) या माउस क्लिक से आसानी से अगली या पिछली स्लाइड पर जाएं।
Runs on Low-Spec Lab Computers
यह टूल बहुत हल्का है और पुराने कंप्यूटरों पर भी बिना अटके बहुत तेजी से काम करता है।
