Hello.
When searching in any window (for example H button book), pressing CTRL+A should select all the text written.
For example, if I typed "pickaxe" and read the results, but then want to search for something else, pressing CTRL+A does nothing. I have to manually delete everything letter by letter and type the new query again. Instead, being able to select all the text with CTRL+A would allow me to quickly overwrite it with the new word, improving usability.
Ps: Also double click for choosing a word and triple click for choosing all words don't work, too.
