I am often working in a browser and sometimes browsers can make really long hotstrings go really slow. Since some of the strings I use can be several paragraphs, it was a problem. So, I found a solution that works really well. Copy your string to a variable and use the Clipboard to paste. Compare these two methods below. You can see the difference even in notepad, but try using them on a forum or in gmail (or anything brower based) and you will really see the difference. And by being fast, it is also more reliable since mouse clicks and keyboard presses have less chance to interrupt things.
For the example I am using the beginning of the book A Tale of Two Cities. Run the script and compare the speed of "tale1" to "tale2".
text = It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way—in short, the period was so far like the present period, that some of its noisiest authorities insisted on its being received, for good or for evil, in the superlative degree of comparison only. There were a king with a large jaw and a queen with a plain face, on the throne of England; there were a king with a large jaw and a queen with a fair face, on the throne of France. In both countries it was clearer than crystal to the lords of the State preserves of loaves and fishes, that things in general were settled for ever. It was the year of Our Lord one thousand seven hundred and seventy-five. ; the fast way :*:tale1:: Clipboard = %text% Send ^v Exit ; the slow way :*:tale2::It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way—in short, the period was so far like the present period, that some of its noisiest authorities insisted on its being received, for good or for evil, in the superlative degree of comparison only.
