Sometimes, the selected text has some whitespace at the end, which, if loaded as URL in a browser would cause an error. Enabling this option removes any whitespace at the beginning or end of the selected string (the original clipboard contents will not be modified).
Uaireanta tá beagán spás bán ag deireadh an téacs roghnaithe, agus dá luchtófaí é mar URL i mbrabhsálaí, ba chúis le hearráid é. Leis an rogha seo, bainfear aon spás bán ag tús nó deireadh an teaghráin roghnaithe (ach ní athrófar inneachar na gearrthaisce féin).
