अद्यतन फ़रवरी / 24/2017 : अब संकेतक में वेब लिंक को पिन करने का विकल्प है
परिचय
नोट: इस उत्तर के पिछले संस्करण को संपादित इतिहास के तहत पाया जा सकता है, हालांकि यह अब प्रासंगिक नहीं है।
नीचे प्रस्तुत संकेतक को एक अलग प्रश्न के लिए अभिप्रेत किया गया है, लेकिन जब से अवसर खुद को प्रस्तुत किया है, मैंने इसे यहां जारी करने का निर्णय लिया है। फ़ाइलें संकेतक उपयोगकर्ता की फ़ाइलों और फ़ोल्डरों तक पहुंचने के लिए सरल संकेतक है। यह हाल ही में उपयोग की गई फ़ाइलों, बुकमार्क फ़ाइलों और निर्देशिकाओं की जाँच करने की अनुमति देता है। विशेष रूप से, स्थान मेनू विशेष रूप से इस प्रश्न के लिए प्रासंगिक है।
जैसा कि आप स्क्रीनशॉट से देख सकते हैं, संकेतक अंग्रेजी के अलावा अन्य स्थानों का भी समर्थन करता है, इसलिए यदि आपका सिस्टम अंग्रेजी के अलावा किसी अन्य चीज़ का उपयोग करता है, तो यह काम करेगा।
अद्यतन : संकेतक अब लॉन्च की गई .desktop फ़ाइलों का भी समर्थन करता है जिन्हें पिन किया गया है। उदाहरण के लिए यदि आपके पास फ़ायरफ़ॉक्स है। इस प्रकार, संकेतक को कार्यक्रमों के लिए त्वरित लांचर के रूप में उपयोग किया जा सकता है। लेखन के समय यह सुविधा पीपीए में है (नवंबर 19, 7:53 बजे जीएमटी, प्रक्रिया के बारे में 24 घंटे लगने चाहिए), लेकिन पहले से ही जीथब के साथ-साथ यहां भी अद्यतन स्रोत कोड में है।
सूचक को प्राप्त करना
संकेतक मेरे व्यक्तिगत पीपीए के साथ-साथ गिटहब से भी उपलब्ध है । इसे प्राप्त करने के लिए निम्नलिखित चरणों का उपयोग करें:
